The Neon Blue Goby should be housed in a 10 gallon or larger aquarium. Rarely will it become aggressive towards other fish. However, the Neon Blue Goby is territorial and will demonstrate aggression towards its own kind unless they are a mated pair. It is common for the Neon Blue Goby to spawn in an aquarium, laying its eggs in a crevice or empty shell.
