Overview
The Mayan tetra is an active, peaceful schooling fish for a community tank. It suits someone who has kept fish for a while.
Did you know
The Mayan tetra is one of the larger and hardier members of its genus. That made it a familiar fish in parts of Central America long before it reached the wider hobby.
Caring for the Mayan tetra
Keep Mayan tetras in a school of six or more. A tank of 16 gal (60 L) or larger gives a group enough room. Add some leaf litter or wood for tannins, and shaded planting.
Soft to moderately hard water works, though soft, slightly acidic water suits them best. Keep the temperature at 68 to 79°F (20 to 26°C) and the pH at 6.0 to 7.5.
Mayan tetras are omnivores. A varied diet of quality flakes and small granules keeps them in good shape, with the occasional frozen or live bloodworms and brine shrimp.
Keep them in a community of calm fish of a similar size. They are egg scatterers that give no parental care, and aquarium breeding is not well documented.
Good to know
Hyphessobrycon compressus is a characin in the family Characidae. Its body is laterally compressed, which helps it slip through dense plant growth. It is not considered endangered, though habitat loss is a risk to some local populations.
In the wild
The Mayan tetra comes from slow, shaded freshwater streams and rivers in Mexico, Guatemala and Belize. The bottom there is sand and leaf litter, with decaying plant matter. Across its home range it shows up in everything from clear streams to murky backwaters, a sign of how adaptable it is.
