120 ∗ 30 ∗ 30 cm48 ∗ 12 ∗ 12 in - ~108 litres~29 US gal.

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 also beneficial. Try to arrange the decor so as much of it is off the tank bottom as possible, as the fish moves with great speed at times, especially when startled. It also needs well-oxygenated water, and an efficient filter to deal with the large amounts of waste it produces.

Temperature: Prefers slightly cool water in the range 70-73°F (21-23°C).

pH: 6.0-7.2

Hardness: 2-10°H

An unfussy feeder, it will accept most foods. Offer regular feedings of greens such as cucumber, courgette, blanched spinach etc., as well as live, frozen and dried stuff. It tends to become less of a vegetarian as it grows.

A peaceful species that can be kept with a variety of tankmates, such as larger characins, cyprinids, peaceful cichlids and other catfish. It's surprisingly non-territorial and can be kept both in a species group or other peaceful Loricariids.

This species is sometimes referred to as Hypostomus villarsi, and is a rare find in the hobby. If you're lucky enough to see some for sale, check the fish have rounded bellies and that their eyes aren't sunken before you part with any cash, as these are classic signs of emaciation in newly imported Loricariids.
