Range and natural history
It is especially associated with tubular sponges and also occurs on coral reefs. FishBase lists a recorded depth range of about 7–26 meters, with some accounts emphasizing the deeper part of that range. Sponge structure is therefore a meaningful part of its habitat description.
This association should not be treated as evidence that every sponge-dwelling goby is this species. Several small gobies use reef shelter, so regional occurrence and diagnostic body characters still matter.
