fat sucking cat fish? can anyone explain?

And of course SAEs and CAEs aren't remotely catfish.

actually, out of SAE/CAE/Ottos, I would say the ottos show a more worrisome pronounced fatness (at least some do) when in the tank. Seems to come from no where.... one day they are fine, the next, they look like they swallowed an otto sized basketball.... If the fish is an otto, the belly is common....

if its otos, normal, all my otos are quite fat.
