Habitat
editThis species is the only triplefin that as an adult lives in intertidal zone habitat.[4] It can be observed in tidal pools and has adapted to survive the changes in temperature, oxygen saturation and levels of water acidity that accompany living in that habitat.[4] The abundance of this fish in tidal pools decreases during the winter months.[5]
Prey
editB. medius feeds on small crustaceans including barnacles, molluscs including snails, and amphipods.[4]
