Black and Gold Damsel in the wild.
This video starts out with a yellow juvenile, then moves on to a dark adult with yellow toward the back of the body. Looks like they are inhabiting a Bird's Nest Coral. They become very mean as they grow to their ultimate 5" size, and need a minimum tank size of 55 gallons due to their need to swim about much more than others in their family. Their longer body and forked tail provide them with the speed they need!
Habitat: Natural geographic location: The Black-and-gold Chromis or Behm's Damsel is found in the Western Pacific and the eastern Indian Ocean. Found at depths between 6 - 75 feet (2 - 23 meters). They inhabit passes and outer reef slopes.
Maintenance: This fish will readily eat all kinds of live, frozen, and flake foods and algae. Finely chopped meaty foods (like brine shrimp) can be fed regularly. It is best to feed small amounts several times a day. In a reef situation they don't really need to be fed very often at all.
Social Behaviors: Like all damselfish, they can be territorial and aggressive, especially as they get older. Can be kept together and with other larger fish but watch them closely to be sure their aggression doesn't become destructive.
Breeding/Reproduction: Some of the damselfish have been bred in captivity. See general breeding techniques under Clownfish on the marine breeding page.
