Janss' Pipefish Doryrhamphus janssi

Janss' Pipefish is native to tropical reefs of the eastern Indian and western Pacific Oceans from Indonesia to Japan to eastern Australia. It has an orange body with a blue or purplish-blue head and tail, the latter ending in a black and white flag: black with a large white centre and white borders. It grows to 14cm long.

They work as cleaner fish (gives a new definition to pipe cleaner), usually in pairs, eating parasites from small fish supplemented by plankton and small invertebrates. Related to seahorses, female pipefish pass eggs to the male's brooding pouch and the male incubates the eggs and gives birth to live young.
