The Purple Anthias is also commonly referred as Purple Queen Anthias and Amethyst anthias. It grows up to 6 inches in the wild and should be kept in a tank not less than 35 gallons. Since the Purple Anthias is peaceful, it is imperative to keep it with peaceful tank mates, and not with aggressive tank mates. It does not bother any invertebrates or corals and therefore the Purple Anthias is considered a reef safe species. It is a carnivorous fish that mainly feeds on mysid shrimp and vitamin-enriched brine shrimp that helps in maintaining its color. It is best to feed the Purple Anthias with live foods to make its immune system strong. It should be fed at least three times a day for its continued good health. The Purple Anthias requires an aquarium with lots of ledges and rockwork to relax under. Also, provide it with ample space to swim, and clean, well oxygenated water. The Purple Anthias can be kept ideally in small groups of one male with 5+ females. It starts its life as a female and when required, a female can be changed to male. Male Purple Anthias are much more colorful and often have filamentous streamers which it uses for its mating dance and to deter other males.
