Aggressive Fish - Updated

[noteworthy]

Hello!
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 for him.


What would you guys do?

I've updated the status of my tank on this forum - Aggressive fish is in QT atm and I need help deciding what to do with him.


Current tank inhabitants
1 CC Starfish
2 Crabs
3 Snails
2 Cleaner Shrimp
1 Yellow Tang
1 Damsel

No aggression problems.

The other damsel I had is in QT.

I'd say replace him with a clown or a pair if you have the room in the main.

An extended time out may help, depends on the fish. They are all different.
Its you call.
