No, although they are being bred in captivity. There are two distinct species, differentiated by the spotting on the body. Calloplesiops altivelis has smaller spots arranged in rows the length of the body, C. argus had slightly larger spots scattered randomly over the body. Both fish tend to be rather shy at first, and can be a bit finicky about food. Live shrimp is their favorite, mysis or ghost shrimp depending on size. With a bit of effort they can be trained to overcome their shyness and eat frozen and sometimes even freeze dried krill. They really are an interesting fish to watch hunt live shrimp. They hover over the shrimp with their body bent almost 90 degrees, and then straighten out like a snake striking to catch the shrimp.
