I got a 7" featherfin that's so aggressive that it attacks any fish that stays on the bottom. It will literally chase them and bites. Its in a 125 gal. Anyone have this problem with theirs?
 
My largest nigriventris fights with my red-tail shark almost every day during feedings. He just shimmies around next to him though. No biting.
 
Is there only one in the tank? They're best kept in groups so it may be being that aggro because of being alone

Shave one that has a occasional dispute with my four line Pim but callback down from all the cichlids in the tank even one half its size

I assume its the common featherfin that's at like petsmart, when I looked into them it said best kept in groups and they never leave each others side when I see em in the tanks haha

I had a petsmart synodontis that was not as aggressive as the OP's fish but mine did hold his own in a tank with bichirs... Mine died a while ago so i can not report his "Current" activity. But he was suprisingly tough.

Yeah its the only catfish in the tank and its the syno eupterus. Tankmates are silver dollars 3"-9" and a baby silver arrowana. If any fish goes near the bottom it will aggressively chase them out.

There must be some kind of simple misunderstanding :) S. euptera (= common or African featherfin) are riverine synos, loners when older and usually highly territorial, in sync with many other large riverine synos. IDK if gender matters. Lacustrine synos, e.g., multipunctata, grandiops, petricola, etc. are shoaling at all ages.

Fishnatics, have you looked at my link and the other links therein?
