General Description
Hyphessobrycon compressus, commonly known as the Mayan Tetra, is the type species of the Hyphessobrycon genus within the Characidae family. It is not widely recognized in the ornamental fish trade and is distinguished by the absence of scales on its caudal fin. The species is part of a debated polyphyletic lineage that is currently undergoing taxonomic revisions to define its relationships more accurately. The name compressus reflects the fish's compressed body shape.
Aquarium Setup
The Mayan Tetra requires a well-established aquarium with soft to slightly hard water in the pH range of 6.5-8.0 and a temperature between 20-26°C (see table). The tank should have ample swimming space and be decorated with live plants and driftwood to mimic its natural habitat. Tankmates should be chosen carefully to ensure compatibility with this peaceful species.
Behaviour
In its natural habitat and aquarium setting, H. compressus displays peaceful behavior, making it suitable for community tanks. It is a shoaling species, and therefore, it thrives when kept in groups of its own kind. The fish are active swimmers and enjoy exploring all tank levels.
Feeding and Diet
Being an opportunistic omnivore, the Mayan Tetra consumes a varied diet in the wild. In captivity, they readily accept high-quality flake foods, live or frozen brine shrimp, bloodworms, and small insects. A balanced diet enriched with vegetable matter is essential for their health and coloration.
Reproduction & Dimorphism
During the breeding season, adult male Mayan Tetras develop a darker coloration compared to females. Spawning usually occurs in planted tanks with fine-leaved plants for egg scattering. The adults should be removed post-spawning to prevent them from consuming the eggs. The fry hatch in about 24-36 hours and can be fed infusoria or commercially available fry food.
Habitat and Distribution
The H. compressus species is native to southern Mexico, Guatemala, and Belize. They inhabit smaller rivers, streams, temporary freshwater swamps, and larger permanent lakes in these regions. Sympatric species found in their habitat include Astyanax aeneus and Poecilia sphenops.
