Care

Hypancistrus are small to medium plecos, many with bold patterns of stripes, worm-lines or spots. PlanetCatfish lists about 55 species and L-number forms, from about 4 to 16 cm, with most around 12 cm. Figures here are typical for the group and vary by species, so check the species or L-number before you buy. The best known is the zebra pleco, H. zebra (L046, also once listed as L098 and L173), from the Rio Xingu; it reaches about 8 cm. Brazil banned its export in 2004, so almost all zebras now sold are captive-bred, and they are expensive. Other popular kinds include H. debilittera (L129), H. contradens (L201), H. inspector (L102), and L-number forms such as L236, L260 and L333. For H. zebra, Seriously Fish suggests a base of at least 60 × 30 cm (about 54 litres), with warm (26–30 °C), very clean, well-oxygenated water, pH 6.0–7.5 and some flow. The 80-litre minimum here is our general estimate for the group; larger species need more. Use sand with rocks and plenty of caves of slate, bamboo or pipe, one per fish at least. Males are territorial and defend caves. They develop bristles (odontodes) on the first pectoral ray, which is also thicker, and a broader head than females.

Diet

More carnivore than algae eater: their small, lightly toothed mouths are poor at scraping algae. Feed small, frequent meals of meaty food such as bloodworm, brine shrimp, chopped mussel and prawn, and good sinking pellets or dry discus food. Vegetables are rarely eaten.

Breeding

Cave spawners. The female lays a small clutch (about 7–15 eggs in H. zebra) inside a cave and the male guards and fans them for about a week until the fry are free-swimming. Warm, very clean, oxygen-rich water and a choice of caves sized to fit the male snugly help.

Compatibility and tank mates

Most fish are fine as long as they are not very large or territorial bottom-dwellers. Shy species such as H. zebra are easily out-competed for food, so they do best in a species tank or with calm, small midwater fish. Give each male its own cave to limit fighting.
