Overview
The Cheeya rasbora is a peaceful blackwater specialist that schools in the midwater of a soft-water tank. It needs a keeper with a little experience.
Did you know
The Cheeya rasbora is named for Cheeya, a tall figure in Chinese folklore who hunts ghosts for the lord of death. The describers chose him as a nod to this being the taller, larger rasbora of its pair.
Caring for the Cheeya rasbora
Keep Cheeya rasboras as a school of eight or more, in a shaded, planted tank of 14 gal (54 L) or larger. Build a blackwater setup with botanicals and leaf litter, a dark substrate, dim light and gentle filtration through peat or almond leaves.
Keep the water warm, soft, acidic and tannin-stained, at 72 to 81°F (22 to 27°C) with a pH of 4.5 to 6.5. Chemistry matters more than company with this fish, and it fades and sulks in hard, bright conditions. Feed small foods such as crushed flake, micro pellets and frozen daphnia, cyclops and baby brine shrimp.
Cheeya rasboras are peaceful. Keep them with other soft-water miniatures such as small rasboras and pygmy loaches. Their breeding is not on record in the hobby.
Good to know
Brevibora cheeya is a danio-family rasbora in Danionidae, and one of the larger members of its small genus. It is longer-bodied and longer-snouted than the familiar eyespot rasbora it was separated from. Liao and Tan described it in 2011, distinguishing it partly by its complete lateral line.
In the wild
The Cheeya rasbora lives in peat swamp forest waters of Peninsular Malaysia and Sumatra. These waters run tea-dark, soft and strongly acidic.
