May have made a fish stocking mistake

So I’ve got a 180 gallon tank I’ve just set up that I bought used and it’s established. It’s gonna be fowlr for awhile. I’ve only owned nanos until now. It’s so hard to find fish stock locally And I may have jumped the gun. Right now it’s only got a bar goby and a very small juvenile sail fin tang. I really wanted to add a yellow eyed kole tang and a yellow tang at the same time but nobody had one locally. They’ve been in the tank for 4 days and now my lfs has a yellow and yellow eyed tang. I know tangs should be introduced together but I let the want get the better of me. If I added a yellow or a yellow and yellow eyed kole today or tomorrow would this be trouble? Even if I rearranged rock work? I’d hate for trouble to ensue

Four days is probably not going to be an issue. However, no qt could be. Just to be aware. Good luck. Nice jump from nano to 180g. I jumped from 28g to 210g myself way back. It is a learning curve.

That’s big water with few fish, I think that would work.
Maybe a bit of territorial squirmish at first, but there’s enough water for each.
The issue might be the age of the tank. Both are big eaters (and poopers) and I would be cautious of an increase in nutrients., if your tank can’t process the increase, there’s a chance of ammonia spike, which may suffocate your fish. You could manage that by frequent water changes, good flow and skimming.

Second the quarantine concern and agree space won’t be an issue.

Thanks guys. I do have a skimmer and the tank was running for a couple of years. The live rock was kept in a 100 gallon rubber made tub to keep it live, but I’ll keep the stocking to a minimum until the bacteria build back up, in case needed. I got some fritz 9000 that I’ve been adding a little bit at a time to help keep bacteria established

3-4 days in an isolation tank in the DT will do wonders for reducing aggression to new fish. I speak from experience.

Went ahead and made the plunge... they’re getting along like best friends. Before you mention quarantine, I buy from a reputable vendor who qt all stock
