Anyone have an aggressive syno featherfin?

  • We are currently upgrading MFK. thanks! -neo
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?

Same exact issue with mine he has gotten his own 60 gal to himself now !
However I raised him from 2 inches to almost 7 now

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?

Hmm weird won't be able to find the site but I considered getting some and that's what it said. Maybe the site just had bad material then? Lol its happened to me before so I wouldn't be surprised. The ones I do see in tanks though literally never not shoal.. they are all babies I've seen though so that may be the issue. Maturity inducing territorial aggression

I use to have a s. Eupterus and he did the exact same thing. Super agressive.. but such a beautiful fish. Oh and btw. I started originally with 3 of them. And at abbout 3" or so, they became super territorial to one another and I ended up selling two of them and keeping one solo. So I would def. Second guess the "keeping them in schools" thing imo.

I've raised my two since they were penny sized. Now about 5 inches only the occasional chase away. Each has own cave in 75 gallon

Thanks, mate. I remember your case clearly because it struck me as one of the most vivid and interesting exceptions! Can you please link your thread on this? It had pics too.
 
I have a massive 8 inch Synodontis I adopted (I think he's a hybrid), and I used to have 2 euptera about that size. I've always kept them 1 syno per tank. I tried the 2 euptera in a tank together and within a day one had chewed all the fins, including the spines, off the other. I kept him for 2 years like that with no fins (they never regrew). Now I have just the big hybrid? guy. He lives with other catfish with no problems though (1: 4" spotted pictus, 1: 6" sun catfish, 1: 3" striped raphael, and 1: 7" grass cutter catfish (who swims open water with the cichlids). All of them hold there own with a male festae, a male red devil, a male midas, a large female blood parrot, 2 male flowerhorns, 1 male synspilum, a male carpintis, a female jack dempsey, and a pair of pink fens (all the cichlids are over 4 inches besides the kamalau flowerhorn, most are over 6 inches).
