Pseudacanthicus cf. leopardus

Pseudacanthicus: from the Greek ψευδής (pseudes) meaning 'false', and the generic name Acanthicus.

Mostly collected in the in the rio Negro basin, Amazonas state, Brazil, and in particular the rio Demini, a northern tributary flowing into the central Negro in the municipality of Barcelos.

P. leopardus was described from the Rupununi River in Guyana and the identity of this fish thus remains unconfirmed.

An aquarium with base dimensions of 180 ∗ 60 cm72 ∗ 24 in or larger is required for long-term care.

Not difficult to maintain under the correct conditions; we strongly recommend keeping it in a tank designed to simulate a flowing river with a substrate of variably-sized rocks, sand, fine gravel, and some water-worn boulders.

This can be further furnished with driftwood branches, terracotta pipes, plant pots, etc., arranged to form a network of nooks, crannies, and shaded spots, thus providing broken lines of sight.

Wild specimens are likely omnivorous but with a preference for aquatic invertebrates and suchlike.

In the aquarium it does best when offered a varied diet comprising sinking dried foods, frozen Daphnia, mosquito larvae, chironomid larvae (bloodworm), and prawn/shrimp, for, example, plus some fresh fruit, parboiled potato, etc.

Home-made foods using a mixture of natural ingredients bound with gelatin are very useful since they can be tailored to contain fresh vegetables, Spirulina and meatier ingredients.

Adult males possess a broader head plus more extensive odontode development than females, particularly on the leading pectoral-fin rays and interopercular region.

Cave-spawner with the male responsible for brood care. Has been bred in aquaria.

This 'species' is also traded simply as 'leopard cactus pleco'.
