Newbie here, just joined. Yesterday I brought home three Banggai cardinalfish. They seemed to get along okay, but before I went to bed two of them were obviously paired up and the other one isolated. This morning I noticed that the outcast had his dorsal and caudal fins noticibly shorter.
The only other inhabitants of this 90 gallon tank are two
maroon clownfish. There is plenty of rock and places to hide.
Question: Do I need to get the outcast out immediately or try to let things sort themselves out?
Thanks for any help.
