Galeocharax gulo is a predatory tetra from Peru that grows to a maximum of 25 cm. The word Gealecharax is derived from the Greek words for shark and tetra. Gulo comes from the Greek word for a large weasel species. This betrays a number of character traits that are correct. They are predators that are equipped with long needle-shaped teeth, with which a caught fish has no chance of escaping.
Given the size and the swimming desire of the animals – which should preferably be kept in groups – a very large aquarium is needed. Since Galeocharax lives in fast-flowing rivers, current and clean water are required. The animals are peaceful towards fish that are larger than themselves. They are even somewhat timid, which means that they should not be placed with aggressive species.
