im sorry to rain on your parade howard, but if you are putting this fish into a 12 g nano, the fish will starve to death. a scooter blenny is not a blenny at all. Rather, a member of the mandarin dragonette family which are creatures highly adapted to eating live pods from your rocks and sand. this something that should not be in a tank that is not 6 months mature with at least 40 lbs of LR. so unless you have an established refugium attached to this tank where pods can multiply, the success % for this fish is very low....
