• Dorsal fins - The dorsal fin is located on the backs of fishes. The Black and Gold Chromis has Dorsal fins to lend stability in swimming.

• Ventral fins. The ventral fin is located on the pelvic area of fishes. The Black and Gold Chromis has Ventral fins to lend stability in swimming.

• Caudal fins. The Caudal fin is located on the tail area of fishes. The Black and Gold Chromis has Caudal fins to propel through the water.
