Tometes baileyi
Also known as: Bailey's Pacu, Tapajós Tometes
Origin: Rio Tapajós, Brazil
Tometes baileyi inhabits the fast-flowing rapids and rocky outcrops of the Rio Tapajós in Brazil, where it grazes aquatic plants and algae encrusting submerged rocks. It is considered one of the most endangered serrasalmids due to dam construction in its native range and is rarely seen in specialist collections.
In the aquarium it requires high water flow, well-oxygenated conditions, and a predominantly plant-based diet. Its large adult size and specialist requirements make it suitable only for the most committed keepers. Acquisition should only ever be through verified legal and sustainable channels.
Not subject to piranha ownership laws; legal status as a rare species may apply in Brazil.
Water: 24-28°C, pH 6.0-7.5, moderately soft; high flow rate and excellent oxygenation are essential — replicates rapids habitat. Tank: Minimum 1000L; high-flow setup; smooth rocks and minimal fine substrate; open swimming lanes. Feeding: Herbivore; spirulina pellets, blanched greens, algae wafers; hard fruits periodically for dental health. Breeding: Not achieved in captivity; listed as endangered in the wild. Compatibility: Peaceful; a rare and precious species — ensure all acquisition is through legal, sustainable channels.
