I threw in a bunch of feeders as their occassional treat yesterday. I went our for a few hours and I came back to a VERY swollen catfish. I just got back from work, opened the door and the smell of the tank has taken over the room (the same smell that a feeder tank at the pet shop will have). I see the filter practically plugged up by things that used to look like fish and they're also all over the subtrate as well. My cafish is no longer the fat bastard that he was yesterday. It doesn't look like fish crap. So do they? Do fish puke?
