hi i have a yellow(coral)goby(gobiodon okinawae) in my 12 gal nano it is an awesome little fish for a nano it only grows to about an inch and a half.i feed it regular frozen brine shrimp but when i can get it i try to feed it brine shrimp enriched with spirulina. it is a really cool little fish and it likes to position itself on some of the soft and lps corals in my tank if i had a larger tank i would like to have a mated pair to breed. try one in your nano they are a great little fish.
