Scientific name:Nannostomus marginatus
Synonyms:(none)
Size:2" (5cm)
Origin:South America (Amazon)
Tank setup:Planted tank, with subdued lighting.
Compatibility:Peaceful, community - may be eaten by larger tankmates.
Temperature:24-28oC (75-82oF)
Water chemistry:Soft and acidic preferable.
Feeding:Omnivorous: small live, frozen and dry foods.
Sexing:Adult males are slimmer than females, and may show more red in the fins.
Breeding:An egg scatterer, which is difficult to breed. Provide fine-leaved plants or Java moss and raise temperature to around 30oC (86oF). Hatching takes around two days.
