Additional scientific names
- Rasbora heteromorpha
- Harlequins are from Asia, found from Thailand (Narathiwat southwards) to Sumatra, Indonesia.
- Males are more brightly coloured and have a more acute angle on its wedge of colour on its flanks. Females have rounder bodies.
- A peaceful shoaling fish that should be kept in groups of 6 or more. They should not be kept with large or predatory fish like the Angelfish as they may get eaten.
- They will accept most prepared foods including flake and pellets. Occasional live foods such as brine shrimp or Daphnia will ensure the best health.
- Harlequin Rasboras should be fed once or twice a day.
- The Harlequin Rasbora does best with large open swimming space, as well as some planting. A mature tank with good filtration but not too strong a current is preferred. They prefer slightly acidic to neutral water from a pH of 6.5 to 7.0.
- They are a peaceful mid-swimming shoaling fish. Since they are always on the move, it tends to stress other fish who prefer calmer conditions.
- Trigonostigma heteromorpha is sometimes confused with Trigonostigma espei and Trigonostigma hengeli. The difference is that Harlequin Rasboras has a distinctive black "wedge" shape on its flanks with red/orange around the head and in the fins while the latter two are more slender in body shape than T. heteromorpha, and the black markings, instead of being approximately triangular, has a shape that approximates to that of a Stillson wrench. Sometimes a gold form of T. heteromorpha is seen on the market.
