Im new to this forum, ive been reading discussions for a few months now and finally joined.
I have a problem and dont know what to do.
I have a 20g fresh water tank and last night i noticed that one of my little cory catfish (about 2" long right now) was caught in the filter suction tube
with its side fin. Ive seen this happen before with other fish but they just swim away. This time, i dont know how long he was stuck there for. I immediately turned the pump off and he was able to swim away, however, this morning he has barely any activity and of course wont eat.
So my question is... what can i do to try to help him, unless its too late cuz he has internal damage. And for the future, what can i do to try to prevent it.
I had a 20 power filter that came with the kit from Petco, and the suctioning tube seems to have openings which are too wide for my small fish. I was thinking about wrapping it with some really fine net of some sort... any help would be appreciated!
