Leporacanthicus: Latin, lepus, leporis = rabbit + Greek, akantha = thorn

General Notes:

Leporacanthicus triactis is territorial but generally quite peaceful except with fish of a similar appearance, they can be kept together in a group if the tank is large enough to provide all the fish with a territory. Leporacanthicus triactis produces a lot of waste yet it requires clean well oxygenated water so an efficient filter system preferably with a spray bar is highly recommended. The colour of Leporacanthicus triactis is variable and they can be black, brown or grey.
Lighting should be subdued and both tank decor and substrate should be dark in colour. Live plants will be molested and eaten so use rock work and bogwood to provide caves and territory for these fish.
A feature with all Leporacanthicus is two large teeth which protrude from the upper jaw giving them the name of  'Vampire plec'


Leporacanthicus triactis is an omnivore with a preference for vegetable matter. Use sliced cucumber, skinless processed peas, lettuce, blanched spinach supplemented with algae wafers,  catfish pellets and the occasional live or frozen food such as blood worms.


Adult males have a longer and broader head.


Leporacanthicus triactis is a cave spawner which uses tunnels in the river bank in the wild. It has not yet been bred in captivity.
