Feeding Carnivore although not a predator, prawns and chopped mussel appear favorites and promote favorable growth. High quality pellet foods are well received and greatly reduces the volume of waste produced. Some vegetable should also be provided and thus balances diet.
Furniture Adequate coverage for this Genus is required. Multiple structures consisting of wood, caves, and overhangs are ideal. High intensity lighting does not bother them and many species will 'sun themselves' on the top of the furnishings if they are comfortable with their environment. Long sight lines can promote aggression. Placing structure at different distances from the front glass is an effective solution.
Suggested Tankmates The temptation with large tough Loricariids is to keep them with other large tough fish such as Oscars or other brutish characters. This actually works quite well with most omnivorous or mainly vegetarian plecos. Pseudacanthicus despite their defensive protection can be bullied by faster moving fish of similar size. They are carnivores and only eat vegetables when their preferred food is unavailable. The amount of waste produced depends on their diet but is considerably less than a Panaque or Pterygoplichthys of similar size.
Breeding Unreported.
