One of the still very expensive tetra novelties in the aquarium is the very, very pretty Hyphessobrycon procyon from the Rio Aripuanã in the middle basin of the Rio Madeira. It looks confusingly similar to the kitty tetra, H. heliacus, at first glance. H. procyon and H. heliacus form a species complex together with the also very similar H. peugeoti and H. lowae. For differentiation see the article of Hans-Georg Evers in the journal Amazonas No 99/2021: 22-27, there is also a detailed breeding report on H. procyon.
Here therefore only the most important key data: H. procyon reaches a length of 4-5 cm. They are easy to keep tetras, which have no special demands on water and food. For optimal color and fin development soft, slightly acidic water (pH 6 – 6.5) is favorable, as well as secondary plant matter (peat, dead leaves, alder cones). Aquatic plants are not damaged, H. procyon are very peaceful among themselves and against other species of fish. The males like to display among themselves, which is wonderful to look at and ends without injuries. The best way to keep these tetras is in groups of 10 or more, the sex ratio is not important, but there should be at least two males.
