The Sleeper Banded Bullet Goby, Amblygobius phalaena, features a yellow/white head with blue, orange, and brown dots along with stripes across a grey body. They are very hardy and peaceful, but may become territorial towards other blennies, gobies or dartfish in smaller tanks.

Gobies tend to stay mainly towards the bottom of the tank, burrowing and sifting through the sand. Diet should include a variety of frozen or live mysis shrimp and vitamin enriched brine shrimp 1-2 times daily.
