Stocking advice

[hammerd]

I just finished cycling my tank upgrade (went from 13.5 to 38 Fiji cube) and now I have no idea what to stock in the future. I currently have a royal gramma, a clown fish (not sure the type got him from a friend) and a cleaner shrimp.

Any advice on what to stock ? Any cooler fish that I wouldn’t have been able to stock in the 13.5 ?
