Doryrhamphus

Doryrhamphus is a genus of pipefishes, one of the two genera colloquially known as flagtail pipefishes and are popular in the aquarium trade. The members of this genus are native to the Indian and Pacific Oceans where they inhabit reef environments. The species in this genus have a maximum length of 14 cm or less, with D. janssi being the only species that surpasses 8.5 cm. Most species have a horizontal blue line along their body, and all have a whitish-edged tail that is marked contrastingly with black, red or yellow.
