Hydrolycus armatus

Hydrolycus armatus, also known as Payara or Vampire Fish due to its pronounced fangs, is a striking species of predatory freshwater fish. Not commonly kept in home aquariums because of its size and specialized care requirements, this fish demands large tank setups that mimic riverine conditions. Payara are ambush predators and need careful consideration when housed with other fish due to their natural prey instincts. They are best suited to experienced aquarists with the means to accommodate their needs.
