The Pseudoanthias pleurotaenia boasts beautiful colors and makes a great addition to any reef tank. It is considered one of the largest of the anthias family, and easily attains a size of 4-5 inches. The male Pink Square Anthias should not be kept in a tank less than 45 gallons, and needs an acclimatization period of 3+ hours. It is moderately easy to care for and considered a great schooling fish. The male Pink Square Anthias is peaceful and gets along well with other community fishes. It shows sexual dimorphism; the female Pink Square Anthias is generally reddish pink with a bright pink square and the male is bright orange-yellow in color. The male Pink Square Anthias chiefly feed on zooplankton and benefit from several small feedings throughout the day. The food includes Cyclop-eeze, Mysis shrimp, baby brine shrimp and similar items. If it is only a single male Pink Square Anthias fish, then 25 gallons will suffice for it, but if it is a group then a 75 gallons tank should be used. It requires plenty of space to swim and perch on, therefore lots of rockwork and hiding places is required in the reef aquarium so that it feels safe in the tank and also can reward you by staying out in the open for most of the time. The male Pink Square Anthias requires strong water movement in your tank and should never be housed with fish that are too aggressive. It is completely reef-safe and does not bother any kind of corals present in the nano tank.
