1) Discus Colorful Schooling Freshwater Fish

Discus Fish

Discus fish are very nonviolent, averting conflict via a breakout and intimidation. In full tanks, they’re one of the biggest and brightest fish. The schooling freshwater fish and massive organizations can create a wall of styles throughout the tank.

They tend to live inside the mid-stages. They will rise to the top and dip to the bottom to forage; as a way to effortlessly dominate all degrees of the tank. They do opt to be free-swimming but want the option to be near cover, including massive driftwood or flora inside the tank.

If you are looking for perfect colorful aquarium fish, then Discus fish is one of the first species of freshwater people. They have a good reputation earned. A variety of vibrant colors are available in a combination of lines and dots.

Something about the form in their bodies allows them to reflect their particular colors. Their long and flat sides serve as a canvas for art! Just as the fish are peaceful, there are some problematic situations concerning their care. This species requires very different water restrictions and complicated diets for growth.

It needs to be improved centralized due to complex accommodation and food needs.

Compatibility: 

Outstanding; these edible fish do well with various skills and fish, including many others on this list!

Required Tank Size: 

40 liters per individual; 50+ liters for a small school (4 to 6 discus)

2) Jack Dempsey Colorful Aggressive Freshwater Fish

Jack Dempsey Fish

The Jack Dempsey Fish is a fantastic variety of vibrant colors and styles. We love the electric blue color because of the first level and the bright blue light. The Jack Dempsey Cichlid fish will bewitch your tank, and it is several miles flexible, which means that even if you are a beginner, it will not be a problem to take care of it.

Fluorescent blue light can be hard to find, so be prepared to search if you have purchased in that shade. These species are also tiny. The electrical Blue aggressive freshwater fish skin has a vivid blue color, smaller, and is likewise less aggressive.

This fish has recognition. As we understand, it becomes named after a boxer. Even though this tough and ready fish has a mystery, it has stunning colors, upkeep, and ease of breeding even though it is aggressive. That’s why this fish is so prevalent in home aquariums.

Tending to be greater territorial if stored with only some different fish, therefore allowed to set up and shield a “territory” within the tank without problems. Jack Dempsey cichlids can regularly appear shy, hiding away in cave work.

The standard color has various stripes and bright green dots on the sides, which create a shiny effect under proper light. It is not uncommon to look at a few red on their fins tips. While those fish are powerful, there is something wrong. They become aggressive and can happily fight any fish on their bad side. It is the main obstacle you have to go with regarding their care.

Care Level: 

Intermediate food and care need.

Required Tank Size: 

The tank size fifty five+ to meet the needs.

Compatibility: 

It, like maximum cichlids, is considered “aggressive,” however it can get along in a nicely-populated tank with big fish.

3) Peacock Cichlid Colorful Semi Aggressive Freshwater Fish

Peacock Cichlid Fish

The peacock cichlid is a lovely, long fish with large fins on its back. Males were bred selectively for a variety of bright colors. This type is impressive and can stand out from any tank. One of our favorite things about this fish is the variety of different species available.

A number of the most popular species include:

  • Red peacock cichlid.
  • OB peacock cichlid.
  • Blue peacock cichlid.
  • Strawberry peacock cichlid.
  • Dragon blood peacock cichlid.

It gives you the flexibility to choose between expanding different colors. A few colorful semi aggressive freshwater fish are blue, some are bright yellow, and a few in many red varieties.

Peacock cichlids can grow up to 6 inches long, and adult males are colorful semi-aggressive freshwater fish while females are near them. Therefore, if you need a collection of them, you need to maintain a male and female ratio of 1: 4 in the tank.

Those fish come from the great Lake Malawi (the 9th largest lake among other countries), and their colors will vary greatly depending on the lake’s location. We prefer the type of strawberries, but they are all excellent!

The peacock cichlid is extremely powerful and needs caves, rocks, driftwood, and plant life to mark its location. Unlike other cichlids, Peacock is extremely clean. We advise aquarists who want colorful fish without much hassle.

Easy Care: 

It’s easy for beginners to take care of them.

Consistency: 

Only one species should be allowed in each tank to reduce aggression. Cichlids resemble the concept of different cichlids (they differ with the help of species), as well as a small, medium-sized community or school fish.

Required Tank Size: 

55 + liters.

4) Gourami Colorful Non Aggressive Freshwater Fish

Gourami Fish

Gourami is one of the most popular genres on this list and a colorful non-aggressive freshwater fish. They are not very successful. They are not unique in any way, yet they look good too.

Those fish stand out from any freshwater tank with shiny colors and fun styles. While you combine this with that, they spend their time near the place. You have a fun way to incorporate shiny colors that are always out of the way.

Gouramis is remarkably advanced and, as a result, is well-suited to most community aquariums. Choose non-competing tank mates of the same size.  There are so many Gourami one-of-a-kind styles, yet we have some favorites. Dwarf Gourami, Glorious Gourami, Honey Gourami, and Pearl Gourami are varieties we recommend to anyone.

Gourami will eat almost any food. However, it is essential to change the diet to create a balanced diet. A combination of flake dry food and frozen and fresh/organic ingredients will provide a well-rounded meal plan.

Not only are these tropical fish attractive, but they are also poorly maintained (popular). As long as you find the right type of accommodation installation and do not associate with incompatible types, they’re a breeze to very own.

They do well in planted tanks, so this is not your fish if you can no longer get into the abundant water. We like brightly colored fish with green plants so, in our opinion, it fits heaven!

Make sure you keep the water smooth. Just as you would in an average aquarium, make small water changes, but avoid accidentally removing small fry. You will probably grow up with more surviving fish than you can handle, so you try to find people to shop for or undertake.

Care Level: 

Easy to intermediate

Compatibility: 

Gourami is slow-moving and well-maintained with fish of the same size that is not finned nippers or highly active.

Required Tank Size: 

10 to 30 gallons depending upon the specie

5) Electric Blue Acara Exotic Colorful Freshwater Fish

Electric Blue Acara Exotic Fish

This exotic colorful freshwater fish is undoubtedly one of our favorite fish of all time because of its magical and vibrant shades. The fantastic blue view never fades. This type looks like a shiny blue missile passing through a tank!

What exactly, these swimmers do not start in aquarium life and are kept in the tanks for many years, but it seems that they are probably experiencing the latest increase in recognition.

They make a beautiful yellow line running along the top edge of their back fin. There is a slight yellowness in their caudal fin. This color combination is perfect. Andinoacara pulcher cichlid has fins where you can place those same shades, as well as a dorsal fin that moves quickly as it swims in the water.

The most prominent part of this fish’s primary data is how long it lives, and despite its relatively small size – it can last up to 10 years! It is a long time for a fish, as it can live longer than a big dog!

Their head is not as strong as its overall appearance. It’s colorful freshwater fish for beginners. Worrying about blue Andinoacara Pulcher cichlids is usually not too severe, and the electric acara blue is one of the easiest fish to keep as it requires little or no.

This freshwater fish resists and adapts easily to new and changing conditions inside the tank, but one thing you want to make sure of is that there may be enough open space to swim. Another reason why we serve these fish is their attitude and the level of care required. Unlike other fish on our list (especially cichlids), this species is unique.

If you want a color splash without violence, remember Blue Acara electric. Having a green electric acara is a big responsibility, and you always need to make sure you tend to take care of it all the time as many pet stores do not like to accept fully grown fish.

Care Need: 

Beginner to intermediate.

Temperament: 

They live peacefully with other aquarium members.

Tank Size: 

Thirty gallons tank is required.

6) German Blue Ram Colorful Community Freshwater Fish

German Blue Ram Fish

This most colorful community freshwater fish has one of the unique exterior patterns. Just as some species of animals on our list have a wide range of colors and styles that occur behind their heads, the German Blue Ram has things that happen everywhere!

German rams (also known as Ram Cichlid) are among the top colorful freshwater fish and a famous cichlid, with yellowish bodies and beautiful blue dots that protect the stomach, tail, wings, and distinct black stripes with their shiny purple eyes.

The first thing you will observe about this fish is the long black stripes running over their eyes. They usually have a dot on the front of their dorsal fin and in the center of their body.

Males have an extra sharp fin, and females tend to be smaller and have an orange-pink belly. It gives them the kind of “punk rock” look we love. The back of their bodies usually has a tone of tiny dots that smooth out their fins (this shifts the piece primarily based on the template, though).

While installing your filters for German blue ram, you will want a minimum of 20 liters per pair, with lots of vegetation and hiding places. The rams like to sit and expose the area in the middle and back of the tank. Even though these are peaceful fish, they can grow up competitive with other rams in the area. Our favorite colors are an orange body with bright green dots and a yellow body with purple stripes.

These are good clean fish that you should keep safe. They are nonviolent, they do not care, and instead, they are small. You will need to be a skilled aquarist to catch these excellent fish as they considerably affect the boundaries of poor water (especially nitrate levels). They require regular weekly water changes.

Care Need: 

Amateur and low-maintenance fish with great value.

Temperament: 

It isa magnificent, very social fish.

Tank Size: 

30 liters or more.

7) Boeseman Most Colorful Rainbow Fish

Boeseman Rainbow Fish

These species have a more straightforward color pattern than other fish on our list, but that does not mean they are not attractive! There’s all about this smooth look that we like. The front half of the most colorful fish is blue-gray, and the back half is orange-yellow. No fancy styles, lines, or dots are present.

If kept with various species such as tetra, Discus, guppies, or shrimps, for example, Peaceful public fish can create a fantastic tropical aquarium and presence. These fish are so abundant that they are a delight to observe at certain times of the day. They will never take a break and want to know something happening in the aquarium.

This type of rainbow fish is precise with its color, which begins as silver / gray on the head and will be a bright yellow/orange near the tail. It is essential to pay close attention to water restrictions when buying this fish. They may be more sensitive to water-based adjustments and not have comprehensive operating parameters.

Rainbowfish grow to be a male of 3-4″ and is very happy to be kept at 6 to 8 companies. Boeseman rainbow fish also need dense leaves inside the tank to reach an open swimming pool to create conditions in their natural habitat.

Easy Maintenance: 

It is moderate due to tank requirements.

Compatibility: 

It is perfect. However, you should keep it with other fish of the same length to avoid scaring small fish. Active tanks include dainos, cichlids, catfish, or a different rainbowfish.

Required Tank Size: 

30+ gallons.

8) Flower Horn Cichlid Colorful Friendly Freshwater Fish

Flower Horn Cichlid Fish

Even if you take the color out of the equation, flower horn cichlids are just a sight to behold. With their nuchal hump (large lump on their head), they bring an unmistakable look to your tank. Flower horns are among the most beautiful and colorful friendly freshwater fish for aquarium enthusiasts. Usually, flower horns have light pink/orange heads that fade into white/gold bodies with black spots near their backline. These fish are available in a combination of attractive shades, but the most common are bright red and white spots on their whole body.

There will also be a few black strips going down their center line and occasionally in their hump. The upper bouts featured two cutaways for easier access to the higher frets. Special color schemes always include specific tail conditions. There are so many types to cover.

You will see white spots more dominant than red from time to time. It is our favorite version, in my opinion, but it may be hard to find. Their large, thick bodies, round lips, and nuchal stump make them the centerpiece of the entire aquarium. These fish are knowledgeable and have formed close bonds with their owners.

There are a few beautiful animations in the line of owners stroking and feeding their Flower horns! Cichlids with very fierce flower horns must become isolated in a 75-liter tank. It is possible to live in a pair (one hundred and fifty-liter tank) if they were together and if you think they are young and grown together.

The real tactic of this fish is its length and agility. These suckers can have an evil heart! Its size means that you will need a few spaces in your big tank home. These features make them less attractive to the newbie, but they can be remarkable fish.

Care Level: 

Beginner

Required Tank Size: 

55+ gallon

Compatibility: 

Low, flower heads may compete and interact poorly with tank participants. It miles recommended providing a personal tank for flower horns to avoid causing pressure on small fish. While in my opinion, they can be a satisfying fish with significant benefits in size and beauty.

9) Oscars Colorful Freshwater Fish for Community Tank

Oscars Colorful Fish

These species of cichlid are omnivores. They come from rivers and lakes within the Amazon River. The colorful schooling freshwater fish are opportunistic suppliers to consume various foods, including small species of insects, crustaceans, and many invertebrates. They will eat flowers, fruits, and seeds.

Without any query, Oscar Fish deserves a place in our list of colorful freshwater fish for community tank. This type has a combination of adorable orange and dark-looking glitter. Their bodies are dark orange spots and stretch marks on their body.

Oscars are another type of cichlid list of colors, shapes, and sizes. Like the pigmentation of the high notch, the Oscars are also famous for their ingenuity among other fish species. Some Oscars are said to play and engage with their owners and show signs of “happiness” when their owner enters the room.

Within the appropriate lighting fixtures, this may seem a bit intimidating. It is especially true when you learn about their ability to be aggressive near different fish. The Oscars live longer. They can last for 20 years. If you decide to have an Oscar, be prepared to keep it for decades because the Oscar is human-friendly, many owners end up sticking to their fish over the years.

Another side of the Oscar fish is the cichlid’s ability to become aggressive that often occurs in those fish. It is possible to stay with the Oscars and friends of the tanks. They come up with commitment and visibility that allows you to stay away from the Oscars that show anger.

Those fish are tough and will not hesitate to attack different fish that rub them incorrectly. However, if you keep them in an empty tank, that is a long way to go. If you follow the recommended care instructions, then those fish are the options for you. 

Decorating an Oscar fish tank can be a chore. Oscars are big fish and will be strong enough to move small objects and break up plants in the aquarium. A large stone or driftwood needs to add to the aquariums as a centerpiece.

Level of Care: 

Medium-high due to its unique location and “character” requirements.

Compatibility: 

The Oscars need ample space to minimize the chance of competing behavior, and the friends of the tanks should be brought in with a fantastic sight.

Required Tank Capacity: 

55+ gallons 

10) Fancy Guppy Colorful Freshwater Fish for Small Tanks

Fancy Guppy Fish

Fancy Guppies are an attractive fish that is growing in popularity these days. Even though those fish have always been an unusual food for the aquarium, recreational activity seems to spike. Cute guppies are some of the colorful freshwater fish for small tanks found because they are smooth to reproduce.

It is also one of the most popular and versatile species in aquarium evolution. One way to describe the shape of these colorful freshwater fish for small tanks is as the extended Bettas. They have a comprehensive and narrow frame but have a similar caudal-like fan that flows after they move.

There are so many shades, styles, and tail types available. There is an extension of the colors and styles you can find in those fish. We love Dumbo Ear because of the red leopard-like pattern on the tail. A large group of guppies in a network tank do an eye-catching bath in the shade. They will come together close to the top level of your tank.

They are also very accessible and clean to take care of themselves. You can store it in good tones in any tank, and they will not cause any problems. In addition, they are extreme, which gives you a small area of ​​light in terms of water boundaries.

11) Duboisi Cichlid Coolest Freshwater Aquarium Fish

Duboisi Cichlid Fish

Duboisi Cichlids are fabulous distinct freshwater fish species, with their robust structure, large heads, and a caudal fin shaped like a fan.

After they are young, they darken with shiny spots on their body. They look like a night sky! As they grow, those spots begin to fade and extend an extensive yellow line about one-third of the path and from their head (which turns blue).

The small douche is a deep black body covered with straight lines of green/white dots. As they grow older, their color changes. Duboisi is one of the many species of Tropheus cichlids, famous for their extraordinary level of activity and individual personality.

Those cichlids are experiencing color and pattern changes as they grow, making them a particular favorite for color seekers. This exciting alternative leads to many aquarists expecting to face different species when seeing images. The difference is enormous!

The spots of a fully grown Duboisi will fade, its head will be deep blue and extend a bright yellow band near their pectoral fins. Juvenile duboisis is black with greenish-white spots, and as the fish grow, they lose the dots and gain a blue head and a yellowish-white band in the middle.

They are well-preserved in the tanks of some fish species in about 8-10 fish schools due to their solid social structure and competitive environment. This coolest freshwater aquarium fish can be very competitive, requires professional care, and should be kept in a well-functioning animal tank with a minimum length of 6.

It is possible to gradually settle Duboisi cichlids and other Tanganyikan or Malawian cichlids competing. However, I would not suggest this to a newcomer. Those colorful community freshwater fish are flexible when it comes to water boundaries. However, their competitive behavior is something you need to observe. 

Care Level: 

Intermediate to Advance.

Compatibility: 

Due to their aggressive nature, they need special containers.
