Labroides dimidiatus - The Bluestreak Cleaner Wrasse is also known as the Common Cleaner Wrasse. In an aquarium 30 gallons or larger, it needs to be kept with a large number of community fish which it can clean and thus obtain food. It can greatly reduce the risk of parasites, which it eats off other fish. It may accept substitute foods such as chopped seafoods, brine shrimp, and live black worms. It should be fed at least three times daily. This species of Cleaner Wrasse is more hardy than the others, but is still difficult to feed and maintain, and should only be kept by experienced aquarists.
