Blue line Grouper

[deric]

I want to put in a few cleaners mainly crabs with my 4inch grouper. There is also a 4 inch moray in there. Would these be compatible?

The crabs would be eaten by both of them.

inverts with those guys will have no chance just make a good snack .
avoid any small fish also as if it fits in there mouth they'll eat it .
