Overview
Keep six or more with small peaceful tankmates. It takes crushed flake, granules, and frozen daphnia or brine shrimp. As with most freshly described tetras, captive observations are still being written by the first keepers to hold it, so notes are worth keeping.
In the wild
A recently described Brazilian tetra from soft interior waters. Keep it the way the rare-tetra playbook says: dark substrate, wood and leaves, gentle filtration, 22 to 27 degrees Celsius, and pH 5.5 to 7.0.
Good to know
Hyphessobrycon procyon reaches about 3.8 centimeters and is a recent addition to the genus, still thinly documented beyond its description. It shows a prominent dark caudal-peduncle mark that reads like a taillight at the base of the tail.
Did you know
Procyon is also the name of one of the brightest stars in the night sky, fitting for a fish whose tail-base blotch flashes like a beacon when the school turns.
