Hypostomus regani

Brazil, Paraguay, Uruguay and Argentina.

No specific details are available.

48" x 18" x 18" (120cm x 45cm x 45cm) - 243 litres is just about adequate for a single fish, but a much bigger tank would be needed to house more than one of these.

A spacious tank is required, preferably with a sandy substrate. Provide hiding places and shade with some big chunks of driftwood and smooth rocks. Dim lighting is beneficial, and use a powerful filter to deal with the large amounts of waste it produces. Any plants are likely to be uprooted but hardy species that can be attached to decor such as java fern or Anubias may survive, as will floating varieties.

Temperature: 24 – 28 °C75 – 82 °F

pH: 6.0-7.0

Hardness: 5-10°H

An unfussy feeder, it will accept most foods. Offer regular feedings of greens such as cucumber, courgette, blanched spinach etc., as well as dried, live and frozen stuff.

A peaceful species that can be kept with a variety of tankmates, such as larger characins, cyprinids, peaceful cichlids and other catfish. It's territorial with any similarly-sized bottom dwellers, especially conspecifics, so a very large tank is needed if any other large catfish are to be kept.
