Malawi bloat is a common disease to many acaras: this is why it’s sometimes called cichlids bloat. Additionally, there may be respiratory complications, in which case the (influenced ) fish begins to breathe fast; inner organs like kidneys and liver may also be adversely affected, and the fish’s stool becomes discolored and stringy.

Praziquantel is the most vital and widely used medicine for treating skin fluke infestation.

Freshwater Ich: 

Freshwater ich has widely reported influencing electric blue acaras even as it will hamper the wellness of an array of other freshwater fishes. An infected electrical blue acara develops a white spot on its skin; scratches its own body against hard objects; loses desire, and suffers respiratory issues, which may make it arrive at the surface, gasping for breath.
