Taxonomy
- Family: Loricariidae
- Genus: Hopliancistrus
- Scientific name: Hopliancistrus tricornis
- Trade code: L017
Habitat
The species occurs in South America, in the Tapajos and Xingu river basins of Brazil. According to FishBase it is a demersal, bottom-dwelling fish of tropical freshwater. All described members of the genus are reported from the Para state of Brazil.
Tank requirements
- Minimum tank volume: 200 L
- Temperature: 24-28 °C (75-82 °F)
- pH: 6.0-7.5
- GH: 2-12 °dGH
- Water flow: moderate, well-oxygenated
- Lifespan: about 8-12 years
As a loricariid it needs driftwood, caves and clean, well-oxygenated water.
Diet
This catfish is an omnivore. In the aquarium a mixed diet that combines vegetable matter with occasional protein foods suits loricariid plecos of this type; feeding once daily is appropriate.
Compatibility
Hopliancistrus tricornis is a peaceful, bottom-dwelling and largely nocturnal fish. Calm mid-water companions such as tetras and corydoras are suitable, while other territorial or aggressive plecos are best avoided to limit competition for caves.
Breeding
It is a cave-spawner. Breeding in captivity is considered advanced and is rarely reported, in part because the species is uncommon in the hobby.
Conservation status
IUCN Red List: Endangered, assessed in 2018. The restricted river-basin distribution makes the species sensitive to habitat change.
