I'm in the process of setting up a new reef aquarium, and I'm looking for stocking advice. The tank is 10 gallons, with 20 lbs of dry rock. With the rock and sand the tank holds approximately 7 gallons of water. I,m thinking of adding a firefish as well as a peppermint shrimp. However after checking live aquaria I think a better option may be a few neon gobys. If any experianced saltwater fishkeepers know please let me know if a firefish is a good option.
