Thats a good price man... They're really not evil when they're small... There's a good chance that I'm gonna have to split up the crew within the next year... but for now there completely chill... The jar I have was housed with discuss fish at the local pet store... But if you don't mind a single resident tank that Jar is a great fish... Also others have been successful keeping them in larger communities with fish like large Pacu and other larger none aggressive species.... but it seems to only work few and far between. For now I'm crossing my fingers and keeping a close eye on them!
