I have a malawi tank with some marble aulonocaras amongst other fish. They are getting really big and have huge appetites - gobbling up as much as they can as quick as they can As a result of this they are getting pop-bellied. Or could they be suffering from malawi bloat. They seem fine, swimming around, no other visual problems - just fat. Do I have a problem or am I just imagining things - being the over protective mother that I am
