Yeah Well He's Just Stressed I ThinkI never had one of those.. but.. generally speaking.. I would scrutinize your water parameters and maybe give him some cover to help minimize stress.
OK now he's on the surface but isn't eating anything"just stressed"... is enough to easily kill fish. From what I read, aro's are particularly susceptible. I would give him cover on both surface and floor of tank.
Yes I know but I did not but it...it was an accidental gift so..What size tank is he in now ? it should be in at least a 120 gallon tank and in that picture he will kill every fish in that tank..if he lives that long..sorry to be rude but you should do your research before buying any fish.
