Neon gobies are from Florida and the Caribbean Sea, and are one of the most easily recognized and popular saltwater aquarium fish. It is well documented that this fish is a cleaner species that picks parasites and other debris from the mouth, gills and skin of larger fish. They are small, reaching about 2 inches in length, and are black with two neon blue stripes along the back and a white belly.

Neon gobies are not difficult to keep in aquariums, and are especially well suited to reef tanks. They will eat small bits of frozen and dry aquarium foods although in nature they are almost exclusively parasite pickers. Normally, they are not bothered by larger fish because they are recognized as cleaners. They can fall victim to mantis shrimp, pistol shrimp and other ambush feeders sometimes present in the live rock of reef tanks. Spawning of this species is well documented, and pairing and spawning are often observed in aquaria. This species can lay 500-800 eggs every 10 days, hatching in about 8-9 days. They spend about 25-28 days as larva until metamorphosis.
