Did you know
The Clavatus tetra's club-shaped shoulder blotch works like a maker's mark. In a shipment of assorted Peru tetras, that one smudge identifies it at a glance.
Caring for the Clavatus tetra
Keep Clavatus tetras in a group of six or more, in 15 gal (55 L) or larger. A planted or leaf-littered tank with gentle filtration suits them.
Keep the water soft and stable, at 72 to 81°F (22 to 27°C) and a pH of 5.5 to 7.2. As with most rarely imported tetras, that does more for their color than any food can. They accept crushed flake, micro granules and small frozen foods.
Clavatus tetras are peaceful. Keep them alongside other small, peaceful Peruvian species like pencilfish or dwarf cichlids.
