Aquarium Compatibility

Because it feeds mainly on floating plant material and zooplankton, it is a possible candidate for the reef aquarium. However, in nature, and in captivity, it will occasionally nibble on sessile invertebrates. It may also harass ornamental shrimps that are introduced after it has become adjusted to its captive home.
