Interesting Facts and Information - Why are Green Chromis slimy?
Green Chromis secrete a type of mucus, or slime, from their skin. This slime provides protection against parasites and infections and helps the Green Chromis to move through the water faster. Some fish species also release toxins in their slime which ward off enemy attacks. Other fish species use their slime to feed their young.

Gills enable the Green Chromis to breathe. Gills consist of thin sheets of tissue containing blood vessels. As water passes over the gills oxygen is absorbed into the blood stream Carbon dioxide passes out into the water. The gills are protected by a large bony plate called an operculum. Some fish species however have lungs and breathe air.

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

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

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

• Pectoral fins. The Pectoral fin is located on the breast area of fishes. The Green Chromis has Pectoral fins to for locomotion and side to side movement
