returning a tang

[Aaronreef]

Hello everyone.

So Ive just introduced a new fish a week ago
I have a purple tang that's a bit aggressive to new fish
so I took him out and wondered how long people would leave it before I put him back in?
He has been out the tank a week now the new fish seems very happy no other fish both him they all seem to be getting along
I know if I put the purple back in and he starts his aggression I won't be able to catch him as he'll know what's happening

How long would you keep him.out for?

How big is the tank, and what are all the fish in it? What new fish did you add?

Tanks about 260gallons
2 clowns
Fire fish
Starry blenny
Midas blenny
melanurus wrasse
Banana wrasse /silver belly wrasse
Scopas tang
Just added a copper band and a blue cheek goby
Removed the purple tang as he is the aggressive one the scopas isn't an issue

7 - 14 days tends to be the norm for keeping aggressive fish in time out. Ive done 7 a few times and its worked.

Either way, when you reintroduce i would put the purple into an acclimation box - Let both show whatever interest they are going to without the ability of actually causing damage if thats the case. If there is still big aggression, then it may be a case of removing for good.

For what its worth - An acclimation box can be as simple as eggcrate fixed into a rectangle with cable ties and a magnet to keep it in place. Doesnt have to be fancy, just something large enough to house the fish for a day or two to observe.
