Overview

A blackwater schooling tetra that suits a cardinal-tetra style tank. Keep ten or more in a 75 liter tank with soft acidic water, leaf litter, wood and dim light, which is what deepens the red line along the body. It is peaceful and takes fine flake, micro granules and small frozen foods. In bright, hard water it stays washed out no matter how well it is fed.

In the wild

Hemigrammus rubrostriatus lives in the blackwaters of the Colombian Amazon, in soft, acidic, tannin-stained water among submerged litter. Keep it at 23 to 28 degrees Celsius and pH 5.0 to 6.8, with gentle flow and low light.

Good to know

Hemigrammus rubrostriatus reaches about 6 centimeters and carries a red stripe along the flank that intensifies with water darkness and condition. It is an egg-scattering, non-guarding spawner. Hemigrammus is separated from Hyphessobrycon mainly by having scales extending onto the base of the tail fin.
