Overview

Coppery pink colouring and a bold black wedge make Harlequin Rasboras easy to recognise. A settled shoal brings gentle movement to a planted aquarium.

English name Harlequin Rasbora
Latin name Trigonostigma heteromorpha
Origin Malay Peninsula and neighbouring Southeast Asian waters
Adult size 4-5 cm
Typical lifespan 5-8 years
Temperament Generally peaceful with appropriate companions
Tank level Middle
Social needs Keep at least 8-10 together.

Tank Setup

Aquarium size At least 60 litres, with a 60 × 30 cm base; allow more space for a community.
Temperature 23-27°C
pH 6.0-7.5
Hardness 2-12 dGH
Water type Freshwater

Plant the sides and back, leaving a clear swimming area. Floating plants and shaded retreats help the shoal settle.

Behaviour & Compatibility

Peaceful with small, calm companions sharing the same water conditions. Avoid large predators and persistently boisterous tankmates.

Diet & Feeding

Offer fine flakes or small granules, with small frozen or live foods such as daphnia and brine shrimp.

Routine Care

Use a fully cycled aquarium before adding livestock. Check temperature, appetite and behaviour daily. Test water regularly: ammonia and nitrite must remain at zero. Make regular partial water changes with conditioned water matched to the aquarium's temperature and chemistry. Keep nitrate low and rinse biological filter media in removed aquarium water.

You can order online for Click & Collect. We will confirm when your livestock is ready to collect from Newlands Home and Garden Centre, Clondalkin, Dublin 22. We do not deliver live fish or aquatic invertebrates. Please have a suitable, fully prepared aquarium ready before collection.
