Open water nano reef fish recommendations?

[20gallonreefer000]

I have a 1.5 year old sps dominated 20 gallon and am looking for a small and relatively peaceful fish to add for some movement. I currently have a pair of chalk bass so something that isn't blue or red would be nice. Any recommendations are welcome, thanks :)

How is the chalk bass pair doing in your tank? Heard they can get pretty big.
You can always try a blenny in your tank. Perfectly peaceful fish with a lot of personality

The chalk bass are great, very fun fish to watch when they are out. A blenny is an option, if I can find a tail spot I’ll definitely get one.
