The Serpae Tetra are known to inhabit densely vegetated and stagnant waters like ponds and small lakes in South America; in particular, northern Paraguay.
They are easy to care for making them a good choice for beginners. They should be in a school of six or more and do best in an 80-litre aquarium – as they can harass other fish, especially in a smaller tank.
Lighting in the tank should be dim, and a high-quality filter should be used that doesn’t cause too much of a current. Substrate river sand, driftwood, twisted roots, woodwork and plenty of plants will make the Serpae feel right at home.
