Adding to my 66g RSM. What next?

[ashr]

Hey all

As some of you know I have a 66 gallon Red Sea Max.

I am looking to add some more fish to the tank and wanted to see what you all thought on what to add next

Here is what I have so far

1x yellow tang
1x green chromis
1x anthias
1x cardinalfish
1x maroon clown
1x bi-color blenny
1x Green Mandarin
1x yellow watchman
1x fire fish



Is there anything else that could be added to this mix? I want to see some schooling so maybe just a few more green chromis?

Also please no tang police. I have had no issues and all my fish are very happy and healthy!
