Help picking new fish

There is so many fish you can have problem might be the order you get them how big is that tang?

 

What type of clown do you have what are you planning for reef tank or fish only, aggressive or passive which can go either way having a scopa in the tank already? Wrasse are beautiful fish but need a roof

 

A top glass wrasse and a few other fish like to jump..... Personally I would look at a lawn mower blenny or a starry blenny as your next choice.... They are excellent clean up crew fish and passive with most other fish unless it is same shape and body style .... I have a 4 inch starry and I call him Paul Sr from Orange county choppers the fish change colours so it is cool to watch

 

Flaming Angels are sweet. Never had nipping issue at all.

 

Yellow tangs are my favorite. With your tank size you're not limited too much. My short list is:
Yellow tang
Blue hippo tang
Purple dotty back
Flame angel
Scooter or lawnmower Benny
Blue/green chromis
Coral beauty
Watchman goby
Most of these are reef safe. The Angels you need to keep an eye on, but their amazing fish.

 

I would do this starry blenny 1 early peaceful unless there is other blenny
Week 1
Chromis I have a school and doing fine so maybe 5 or 6 and your watchman goby and shrimp maybe? Same time or in a few weeks of each other there all peaceful fish

maybe get another clown to go with the one you have.

The dottyback I would pass on unless you want it to chase your chromis and kill your goby, pretty fish not worth the hassle

The two angels same time next say a few weeks after things settle down and your system is stable

And the tangs same time, since the hippo and scopa are close in shape I would go for a 3 inch or bigger blue and if the fish still fight try to rearrange the whole tank it has help me once. i still would do a wrasse over the dotty back but watch out on what you get some are mean others are timid .... Exquisite is a nice middle of the fish
