Habitat and Ecology [top]

Habitat and Ecology:	Doryrhamphus janssi is found in tidal pools and sheltered inner reefs, usually in caves with sponges and below large coral plates. Doryrhamphus janssi is an active cleaner and has a cleaning station that is regularly visited by apogonids and damselfishes where adults work in pairs (Kuiter 2000). Males carry eggs in a brood pouch which is found under the trunk (Dawson 1981) Species of Doryrhamphus typically brood 80-150 eggs (Kuiter 2000).
Systems:	Marine
