🐟 Black Harlequin Rasbora Trigonostigma heteromorpha
Dark Morph • Peaceful • Schooling
 
📋 The Black Harlequin Rasbora is a striking dark color morph of the classic Harlequin Rasbora. It has the same iconic triangular black patch on its body, but with a richer black coloration and darker overall tone, giving it a more dramatic appearance.
Like the standard Harlequin, it is a peaceful schooling fish that thrives in groups of 6 or more. It is hardy, beginner-friendly, and a perfect addition to planted aquariums, where its contrasting dark colors stand out beautifully against green plants.
This variety is becoming more popular in the aquarium trade, offering aquarists a unique twist on a classic species.
