It's a very bad idea to keep a scooter blenny in a small tank. They aren't blennies but members of the dragonet family which require a lot of pods to keep them alive long term. In such a small tank they wil slowly starve to death. They need at least 75Gallon tank with about 100lb of live rock just like the mandarin dragonet does.

Firefish are also very delicate fish that are prone to jumping. They are very timid and slow feeders so they don't go well in tanks with anything that has any sort of aggression.
