Common name:Harlequin, Red rasbora
Scientific name:Trigonostigma heteromorpha
Synonyms:Formerly known as Rasbora heteromorpha.
Size:2" (5cm)
Origin:S.E. Asia
Tank setup:Planted tank with small and peaceful tank mates. Subdued lighting.
Compatibility:Peaceful community fish.
Temperature:22-26oC (72-79oF)
Water chemistry:Fairly soft, slightly acidic (pH 6.0-6.5) preferred.
Feeding:Omnivorous, most foods accepted - flake, granular food, micro-pellets and small frozen/live foods.
Sexing:The black region on males is slightly extended and rounded at the bottom. Females have a straight edge to the black portion.
Breeding:Very soft, mature acidic water required. Remove parents after spawning, eggs hatch in 24 hours.
Comments: This fish is definitely seen at its best when in a larger shoal of at least 8-10 individuals. A well established aquarium with good filtration is necessary to maintain them in good condition. A second species (T. espei) has very similar markings and may also be sold under the name 'Harlequin'.
