Harlequin Rasbora (Trigonostigma heteromorpha)

Quarantined rasbora for planted and community aquariums in Canada.

The Harlequin Rasbora is a classic peaceful schooling fish with copper-orange colour and a bold black wedge marking. It is one of the most reliable community rasboras for planted aquariums and beginner-friendly freshwater setups.

Why This Fish Stands Out

• Classic peaceful schooling fish for planted aquariums
• Bold black wedge pattern with warm copper-orange colour
• Beginner-friendly community fish when kept in a group

Aquarium Setup & Behaviour

Provide a mature aquarium with plants, open swimming space, stable filtration, and peaceful tankmates.

Best kept in a group. Harlequin Rasboras are more confident, colourful, and natural-looking in schools.

Feeding

Feed quality flakes or micro-pellets with occasional frozen/live foods.

Natural Colour & Livestock Integrity

Colour comes from genetics, maturity, health, and proper conditioning. Topick Aquarium does not use hormones to artificially enhance fish colour.

Topick Aquarium Livestock Standard

All fish at Topick Aquarium are carefully quarantined and conditioned to our stable local tap water before sale. Although barbs and rasboras may come from different natural habitats, stable water, gradual acclimation, healthy feeding, and a mature aquarium matter more than chasing exact wild parameters.
