so about a week ago i got a 3 1/2" pictus catfish and put him in my 55 gallon tank then yesterday i got another one at 4 1/2" and put it in with the other one and it looked like they were fighting then i looked it up and it said that they were playing but today the 3 1/2" one`s dorsal fin is complerely shredded up what do you think is the cause?
