Bullet Head Goby

Named for its blunt, rounded profile, the Bullet Head Goby spends most of the day hovering a few inches above its burrow entrance, tail down, ready to drop straight into the sand at the first sign of trouble. It's an unhurried, low-drama fish that does its best work simply existing in the lower third of the tank.
