Interesting Facts and Information - How do you identify the sex of a Brown Discus?
The males and females of many fish species have different colors or different shaped bodies. But there are also other fish species where there is no visible difference. Its sometimes tricky being an ichthyologist!
Interesting Facts and Information - Why are Brown Discus slimy?
Brown Discus secrete a type of mucus, or slime, from their skin. This slime provides protection against parasites and infections and helps the Brown Discus to move through the water faster. Some fish species also release toxins in their slime which ward off enemy attacks. The Discus fish relies on the parents slime to feed their young fry. It is vital that the parents are not removed from the tank or the young Discus fry will not survive.
Interesting Facts and Information - Why do Brown Discus have gills?
Gills enable the Brown Discus 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.
Interesting Facts and Information - Why do the Brown Discus have fins?

Dorsal fins - The dorsal fin is located on the backs of fishes. The Brown Discus has Dorsal fins to lend stability in swimming.
Ventral fins. The ventral fin is located on the pelvic area of fishes. The Brown Discus has Ventral fins to lend stability in swimming.
Caudal fins. The Caudal fin is located on the tail area of fishes. The Brown Discus has Caudal fins to propel through the water.
Pectoral fins. The Pectoral fin is located on the breast area of fishes. The Brown Discus has Pectoral fins to for locomotion and side to side movement
