Guppy Grass Habitat

Najas grass is a North American native found in South America, Asia, and the Middle East. In the wild, you can still find najas in fresh running water. Then whether it’s a lake, stream, pond, pit, waterway, or canal, you’re more likely to get guppy grass. Take a look the next time you go for a walk or a bike ride.


Benefits Of Guppy Grass

Naja grass absorbs ammonia, metals, nitrates, and toxins from aquarium water, so it is a natural aid in the old tank. If you’ve read my article before, you know how much I advocate for a clean tank because it promotes fish’s health.

A clean tank will not only protect your aquatic inhabitants from disease but also reduce their daily stress. Stress-free fishes are happier, live longer, get along well with others and display more vibrant colors. You can promote this overall well-being with common plants that are easy to grow. So there’s no reason not to add some guppy grass to your aquarium.

Smaller fishes such as Danios, Rainbowfish, and Tetras love to use najas grass as a spawning mop. The new fry takes protection under the cover of grass and uses as a nutrient source. The shrimp feeds on the microscopic food found on the Najas grass and appreciates the hidden places it provides.

By absorbing nutrients, guppy grass will not leave enough algae to grow and reduce your cleaning time. You will need to do otherwise.

Aesthetic:

Guppy grass gives your aquarium a great look and improves the aquarium’s visual appeal.

Foods Fount:

Guppy grass is an excellent source of nutrition. Herbivores and omnivores eat this plant independently, and other aquarium residents, including fry, take microorganisms found on leaves.

Hiding Havens:

Many fishes find good places to hide, and it provides safety and comfort in hiding.

Oxygen:

It increases the production of oxygen in your tank to increase the health of the whole community.

Water Washing:

Guppy grass removes metals, toxins, and nitrates from the water to ensure the aquarium’s water quality.

It can reach a maximum height of 3 feet (0.91 m). It is an aquatic plant; you need to make sure your tank is tall enough to support its growth. The leaves are 3 cm long and 1-2 mm wide.

Accommodation and Tank Conditions

As we said, guppy grass grows with less effort, so you don’t need to add CO2, soil, or fertilizer. However, you can use liquid manure if you have soft water. They are habitual to growing quickly in various water conditions. You can choose the temperature and stream that you prefer for your aquatic pet.

You need some surface if you are planting Najas Grass, but what you choose will depend more on what type of fish you are keeping.

For example, if you have a bottom-fed feeder like a catfish, you may need to choose simple sand because rocks damage their underlying.

In terms of lighting, it grows best in low to medium conditions. If the light is too low, your plants will not grow. If the light level is too high, you run the risk of burning and turn red instead of green.

When you are growing and caring for guppy grass, you must be aware of other aquatic plants’ lighting conditions in your tank. If the grass is not mowed and cut regularly, the plants can block the light source for other plants, taking important nutrients and suffocating them.

It is very important to look at the whole community’s needs and well-being.

Size Of The Tank:

Guppy grass can survive in a 5-gallon tank; In fact, the Nano tank will also work, but it is recommended to get a larger tank due to the rapid growth. We recommend at least a 15-gallon tank.

Keep in mind that the size of the tank you need depends on how many fishes are in the aquarium community.

Water Conditions:

Guppy grass is a strong aquatic plant found in numerous water conditions, still or fast-moving, freshwater or choked, cold and hot.

Here are the best parameters to make a close match to their natural habitat are:

  • Water hardness: 5 to 12 dKH
  • Water temperature: 68°F to 79°F (20-26.1°C)
  • pH levels: 6.0 to 8.0 (around 7.0 is best)
  • Water flow: Low for best growth

How Should I Plant Guppy Grass?

The visual leaf appearance will change if the najas grass is planting in the substrate or stays afloat. This is important to memorize because guppy grass is sensitive to changes in conditions, so if you have a floated najas plant and try to plant it in a substrate, you may fail.

If you’re having trouble with a rotting guppy, be patient, and don’t go crazy adding manure in the water. They probably need a little recovery time and space to re-group them. Adding liquid waste can have a steroid effect and cause excessive growth.

If you decide to float your najas grass, divide the stems evenly before placing them next to the water column. If you plant najas grass instead, you still need to split the stems, but you will plant it on a surface of at least two inches.

Tank Mates:

As the name suggests, Guppy Grass markets itself as a “great tank mate for fishes.” It is suitable for small freshwater fish, dwarf shrimp, crabs, and crayfish. It’s also a portion of good food for vegetarian fishes.

Mates of Guppy Grass include:


Maintenance & Care

The best thing you can do for your tank and your guppy grass is to trim it regularly to control its growth. If growth is not controlled, all its algae-controlling properties will disappear. It begins to suffocate other plants and block light sources.

So cutting and pruning every week or two can limit the growth of these lush aquatic plants.

Also, for other aquarium occupants’ safety, be sure to separate it before adding it to your tank. Najas grass can carry parasites, insects, and predators that endanger fish and other tank inhabitants.

It is possible to use pesticides to clean, and it can be toxic to your aquarium for fish and invertebrates.

Potential Problems:

The stems of najas grass are fragile and break easily. Many aquarists complain about the rotting of their guppy grass. Although it is a vigorous plant, it takes time to adapt to the new environment, giving it time to get used to your tank and recover.

Growing (controlling) Guppy Grass:

It is less difficult to grow guppy grass than to control the growth. As it gets bigger and bigger, leaves come out without any trouble. If you clip them, those cuttings will also increase.

You can use clippings in another tank; if you keep a separate tank for your fish, you can put clippings there. You can sell or donate them to your local fish or pet store. Uncontrolled spread of leaves in the water stream can cause real problems.


Is Guppy or Najas Grass Suitable for Your Aquarium?

Guppy grass is considering an invasive species in many parts of the world. It is an excellent addition to your community tank.

One precaution is to control your najas grass’s growth by cutting, handling it by adding it to your compost bin, burying it, or dissolving it in bleach.
