How big is the trigger? Are there other fish in with it already? Has it shown aggression?
Nigers have a pretty broad range of personalities. I'm not sure I'd place a small passive fish in with one.
Trigger is about 3" and there are a few damsels in there with him .
they get along just great. he is very mild tempered. loves to follow you around and rub on the glass when you are close to him, he shows off some
LOL i have a maroon clown that your trigger may wanna watch out for!! I got ten bucks on my maroon clown! Anyone taking bets? jk they should be fine together...
