The Pink Square Anthias, a.k.a. Squareback Anthias, is a large species of Anthias that has a distinct violet "square" in the middle of its body. These fish are a gorgeous reddish-pink color with the square being bright pink in color. These fish are schooling fish and more than one can be kept per tank. The Pink Square Anthias needs lots of swimming room due to its size. These fish also are major jumpers and care should be taken to prevent them from jumping from the tank when doing maintenance. They are excellent for reefs or fish-only aquariums. They will accept most fish foods.The family of Anthias are closely related to Seabasses, which include Groupers. These fish begin life as females and will change sex based on the requirement of their "harem". Anthias gather in huge schools around reefs where they swim within the school waiting for food. These schools can be seen in the hundreds and are made up of small "harems" of a single dominant male, less dominant males, and many females.Photo by saltwaterfish.com member, mx#28
