Overview
The ruby-tinted barb is an active, peaceful filament barb that lives in shoals. It suits a roomy river-style tank and a keeper with a little experience.
Did you know
The ruby-tinted barb looks like one of the recently described Western Ghats filament barbs, but it has carried a scientific name since 1849. Jerdon first recorded it from the Kaveri that year, and only its modern genus, Dawkinsia, is new.
Caring for the ruby-tinted barb
Keep ruby-tinted barbs in a group of six or more. In numbers the males display to one another, and the group settles rather than chasing. They are strong swimmers of the middle water and are in constant motion, so length matters more than fancy planting. A tank of 42 gal (160 L) gives a small group real room to move.
Set up a river-style tank with brisk current, a sand or gravel bed, water-worn stones and some hardy plants. Keep the water at 70 to 79°F (21 to 26°C) and a pH of 6.0 to 7.5.
Ruby-tinted barbs are hearty eaters and take flake, pellets and frozen foods readily, with some greens. They are peaceful and do well with other lively but gentle fish, such as other barbs, larger rasboras and peaceful catfish.
Breeding males grow extended dorsal rays, like their filament-barb relatives. Aquarium spawning is not on record.
Good to know
Dawkinsia rubrotincta belongs to the carp family, Cyprinidae, and was placed in the genus Dawkinsia in 2012. The name rubrotincta means red-tinted, for the ruby wash that spreads through the fins and flank of mature fish. It is also called the rubrotincta filament barb or the red tinged barb.
In the wild
The ruby-tinted barb is native to the Kaveri (Cauvery) river system of southern India. It lives in clear, flowing rivers and hill streams over rock and gravel.
