This blind goby is usually found under rocks in shallow water or surf; sandy areas among rocks in kelp beds, and holes in rocks. It occurs from intertidal areas to 15 m depth. It usually spends most of its life inside the burrow of Neotrypaea biffari (formerly known as Callianassa affinis and Callianassa biffari) (Ref. 92840, 123867, 123870) as it is observed along the east Pacific coast of Mexico and USA (Ref. 123865). Juveniles have rudimentary eyes to find a shrimp burrow. Adults probably never leave the burrow, resulting in the lowest oxygen consumption recorded in FishBase (ver. 05/2018). Monogamous (Ref. 52884). Oviparous (Ref. 205). Parents guard the eggs which are found attached to the walls of burrows (Ref. 56079). Also survives well in captivity.
Oviparous (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).
