This is one of the few Anthias that can be kept with other varieties, e.g.; the Lyretail, Squarespot, and Purple Queen. Use caution when introducing the Red Fairy Anthias to a tank. If there is aggressive or deadly behavior, the fish should be separated. It is best kept in a 125 gallon tank for a group. The Red Fairy Anthias group needs a large amount of room in which to swim.
