Anampses Meleagrides The Yellow Tail Tamarin is also referred to as the Yellowtail Wrasse. It has a black body covered with varying sized white dots. The tail is bright yellow. It requires a 55 gallon or larger aquarium with a 2 inch layer of live sand in which to bury itself. It is a jumper, so a secure lid on the aquarium is required. The Yellowtail Wrasse may be very difficult to keep in an aquarium due to its feeding habits. It eats very small invertebrates (amphipods) that grow on live rock. The diet should also include live, small feeder shrimps (brine, mysid) and finely chopped marine meats.
