Relevant Information:

There are a few similar looking species such as L096, L160 and L375. It is not known yet if these are distict species or just geographical variants of P. spinosus. Aquarium Care: Would need a large tank as they grow big and are territorial. Diet: As with all of this genera they are carnivores and would need to be fed on frozen foods such as Artemia, mosquito larvae, mysis and shrimp. They can also be fed pellet and tablet foods. Etymology: The specific name spinosus: Meaning spiny.

IUCN Red List

Pseudacanthicus spinosus has an extensive distribution in the Amazon basin (from the Napo-Pastaza in Ecuador to the Ilha do Marajó) and may be affected by the construction of the hydrolectric dams in the Rio Xingu and Rio Madeira basins. Although little is known about the population of the species, the aforementioned impacts do not represent substantial threats for their conservation, considering the wide range of distribution. Therefore, Pseudacanthicus spinosus is considered as Least Concern (LC), (IUCN 2023).
