It should have large amounts of live rock for hiding and grazing. These fish enjoy having access to hiding places. We recommend positioning the rock openly so as to create many passages and caves for the fish to swim through and hide in. The Keyhole Angelfish's diet should also include Spirulina, marine algae, seaweed, krill, brine shrimp, mysis or frozen shrimp. Keyhole Angelfish shouldn't be kept with others of its own species (other dwarf angelfish) unless in a larger aquarium.
