The Bumblebee Goby, Amblyeleotris wheeleri, is one of the few gobies that will form a symbiotic relationship with a pistol shrimp. They are peaceful and can be housed with other peaceful fish as well as their own species.
Gobies tend to stay mainly towards the bottom of the tank, burrowing and sifting through the sandy substrate. Diet should include a variety of frozen or live mysis shrimp and vitamin enriched brine shrimp 1-2 times daily.
Love this little guy, He found a home under a rock and comes out and just looks around. I like how fast he is to retreat.
