Want another tang

[reefndude]

I have a 250 g display currently housing a yellow tang, tomini, and a foxface, along with few other small fish. I would like to add another tang or two. Will adding another tang be ok? I also am planning on other smaller fish as well.

Yeah, you got the gallons.
The thing is how to add it to the tank.
The tangs now already in there sure don't want to give up a piece of there space so after your 9 weeks QT you got to acclimate him to the tank in a acclimation box for a week or longer.
Make sure it's a big acclimation box as we talking still a tang here.

How big of an acclimation box are we talking?

How big of an acclimation box are we talking?

At least 5 gallon or bigger.

If you can place a divider - eggcrate, maybe? - in the tank, that might work as well or better. Residents on one side, new arrival on the other.

Adding two tangs simultaneously diffuses aggression.

An acclimation box for 2-5 days will get your existing tangs used to them. If aggression through the box lasts longer than that then the new tangs may not be tolerated in the tank.

Releasing the new fish around lights out helps everyone settle.
