I was wondering how may smaller marine fish there are that can be kept in captivity. I know there are a few gobies that are small but I'm not sure what species are the smallest in that family.

I have a 210 gallon tank with an 80g sump/refugium. I know it's a large tank, but I just want to keep a good number of small fish with lower bio loads.
