Breeding potential: 10. The White Spotted Dorydid has rarely been bred in captivity. Little information is available.
Remarks: Has the ability to make an audible "growling" sound by rotating its pectoral fins. This sound is amplified by the swim bladder. No two individuals have the identical color or pattern. Like other fish of this family, the White Spotted Doradid becomes easily entangled in a net, so a glass jar or plastic bag should be used.
