New fish ideas for established reef

[ReefOG311]

I have a large wrasse, purple tang, 2 clownfish, chalk bass, and azure damsel. I have tried to anthias and sand sifting goby but all died with a few weeks. I have not had luck adding any more fish.
Tank is 90g. Been established for almost 2 years.
Am I stuck with just these 6 fish or should I try again to add? Fish recommendations?

Did the new fish you previously added die because of aggression or some other reason? How much Rock do you have in your tank?

 

[ReefOG311]

Plenty of rock. I think aggression but can't be certain. Just know that adding new fish has been challenging. I leaning towards chronos, or damsels. Maybe even anthias again. Thoughts?

I like the idea of chromis. They are a resilient fish active open swimmers and should add a new dimension to your tank. And did I mention they're inexpensive. Putting multiples in and being active swimmers should help them in case there is an aggression issue.

I agree. How many do u recommend? I have read that folks start off with schools and end up with 1 after all the settling.

I've never really had the major squabbling issues that you see posted. If it was me I would do three.

I have 2 green Chromis in a 40 breeder and these guys fight like cats and dogs, all the time. You'd think they'd give up after a couple years but nope. I had a third, but he was so pestered he jumped out.

I've read in a few places that it's best to add chromis 6 at a time.

Then again, I read it on the internet, so....
