Product Information

Harlequin Rasbora 3cm Information

The fish is a red colour with a black triangular band or wedge that runs from the lateral line to the caudal peduncle and to the base of the stomach. It is sometimes confused with Hengels Rasbora which has similar colour and pattern however the triangular wedge is much bigger in Harlequins.

Max Size: 5 cm


Harlequin Rasboras are not demanding with their food and are ominivorous. Community foods such Tetra Crisps are readily taken. Frozen foods or live foods such as Daphnia are also good.


An ideal community species that is absolutely peaceful and must be considered one of the most peaceful aquarium fish. It actively shoals or schools and is a great addition to any aquarium. Displays best when kept in schools of six or more and kept in a well planted aquarium, with some floating plants on the surface and open swimming areas.

Comments: Harlequin Rasboras are beautiful little fish. They are a schooling fish, so need to be together with other harlequin rasboras. They add a stunning pop of colour to your aquarium when they school together as they swim. These are gentle, inquisitive little fish and are a perfect addition to a community aquarium.

Bottom Line: Yes, I'd recommend this product to a friend
