Harlequin Rasbora

The Harlequin Rasbora (Trigonostigma heteromorpha) is a small, energetic species of rasbora native to Malaysia, Thailand, and Singapore. These fish are popular due their hardiness and small size. Minimum Tank Size: 10 Gallons Maximum Fish Size: 1" Water Temperature: 75F - 85F Ideal pH: 6.0 - 7.5 Water Hardness: 2 - 15 dGH Temperament: Schooling species, peaceful. May be timid in too small of a school. Unless experienced with fish-in cycling, we always suggest cycling an aquarium BEFORE adding fish. Adding fish to a fresh, un-cycled aquarium can kill them rapidly. We offer free water testing at our physical location, and advice via email or call.
