Sexual differences: The distinguishing of the male and female is difficult. Adult males may develop a small lump on their foreheads, but this difference is not always reliable. During the spawning season, the shape of the genital papillae serves as the best difference. It is round in female and pointed in males, although this difference is also difficult to detect.
Breeding techniques: Brown Discus breed like other discus species. See the general description of discus.
Breeding potential: 8. Breeding of the Green Discus is, like all discus, considered difficult.
Remarks: There are many different color variations of the Green Discus. "Royal Green" Discus have dark vertical bands, while the "Peruvian Green" variation has more red spots than other variants. A popular variation, "Tefè Green" has distinct green vertical stripes.
Difficulty of care: 7. The Green Discus requires a varied diet that includes live/frozen foods. The water must be well-maintained and monitored as this species is sensitive to water pollutants.
