Hello, I made a post yesterday about my fish tank becoming a little crowded. To make a long story short I had 5 fish in a 10 gal and then my friend gave me 4 because he could no longer care for them, so Ive had 9 fish in a 10 gal for about 3-4 days. I have 3 angels, an iridescent shark, a clown pleco, 2 lyretail mollies and 2 opaline gouramis. The mollies and gouramis are the new additions. I noticed this morning that one of my angelfish (about the size of a quarter) wasnt swimming well, and then noticed his two side fins were all torn up. This must have happened overnight because I watch him probably the most and he was fine last night. I have him in a seperate container floating in the tank right now, and I noticed that one of the other angels, about his size, seems to want to get to those injured fins. What I'd like to know is 1. Is it possible that it was the other angelfish? Like I said 2 are about the size of a quarter and the other one is maybe half dollar sized. Or could it have been one of the other fish? 2. Im setting up a 30 gallon tonight(only reason it took so long was I had to travel an hour to get it), would this likely make the fish less aggressive? and 3. If I keep him seperate for a while will his fins repair themselves? Or are they like that permanently? Hes really having trouble swimming and keeps getting pushed around by the filters flow. None of the original 5 fish were aggressive to each other, and I havent seen any of the new ones be aggressive to the old ones(just one gourami to the other) so Im thinking perhaps the addition of the new fish stressed out the angel and he attacked the other? Any help you can give would be appreciated. Sorry for the long post, I just wanted to cover all my bases. And I tested the water, everything is fine if that makes a difference in this situation.
