I've moved the fish to a 10 gallon tank and left the other fish in the aquarium with a tang. They seem to be doing fine and there is no aggression in the main tank.
Do you guys think that my damsel I have put in QT
because of aggression will calm down and I could add him back into my main tank? Or should I add some sand and plenty of live rock to keep a 10 gallon tank up for that one fish. I can't get any credit from my LFS
What would you guys do?
