Hawaiian 4-line Wrasse

Pseudocheilinus tetrataenia Four line wrasses are hardy, disease resistant and long-lived. They are similar in requirements to their cousins, the 6-line wrasse; just not quite as aggressive. Once acclimated both these fish will even take care of a few pests in the aquarium, like the pyramidellid snails and commensal flatworms some coral keeping aquarists have to deal with at times. They are considered reef safe as they will not harm corals or coral anemones. Though they can be secretive fish in the wild, once they become acclimated to the home aquarium they can become quite boisterous. They are fine in a community tank but will become aggressive towards shy timid species in the same aquarium, and sometimes even larger fish. To prevent confrontations it is best to keep it with similar sized or larger semi-aggressive fish and to make a single lined wrasse the last addition to the aquarium. They do not co-habitat well with other lined wrasses.
