The Blue-Stripe Cave Goby (Trimma tevegae) has many common names, including: Bluestripe Pygmygoby, Tevegae pygmygoby among others. They can be found throughout the western Pacific Ocean, where they hide among caves and crevices, feeding on small crustaceans and zooplankton. They reach a maximum size of 2 inches, and thus spend the majority of their life hiding in schools among rock work. They should not be housed with predatory or aggressive fish and prefer to be kept in a small school. They should be fed a carnivorous diet of mysis or small crustaceans and can be kept in any tank with at least 10 gallons.
