New tank, new tang and filefish

[shooter2377]

Ok, so I am setting up a new 125 gallon tank with sump. I bought some cycled rock a couple months ago and it’s been sitting in a corner for like two months. I just bought some live rock from gulf live rock (a little disappointed, but not really there fault). I’ve put all this rock in to the tank, had a little ammonia at first, there was a dead clam, but now I think I’m lookin good like a week later. I have some aiptasia so thinking of getting a filefish from biota, and a yellow tang, cause mama wants one and the price doesn’t seem too bad.

I have another tank I’m lookin to combine that has a blue tang in it already. So I want to combine the two tanks.
So my question is, can I get a filefish, a yellow tang, and throw in my blue tang all at the same time in the new tank at the same time after acclimating to the new tank?

I would say all at once as long as you know the tank is ready for it. To mitigate tang aggression dumping all in at the same time is the right decision
