兔甲鲶 · Three Beacon Plec

Overview

Orange fin markings persist into adulthood in Leporacanthicus triactis (L091), although their extent varies among forms. A rapids-dweller with territorial males, it needs oxygen-rich water, adequate floor space, and a diet that includes substantial animal foods.

Distribution & habitat

It comes from the upper Orinoco basin of Colombia and Venezuela, sheltering among rocks and lodged wood in rapids and other fast-flowing reaches.

Aquarium setup

An aquarium around 120 by 45 by 45 cm provides the suggested starting dimensions. Use sand, wood, and smooth rocks for shaded refuges. Dim lighting suits the fish, while powerful efficient filtration, circulation, and aeration must maintain oxygen and process its waste.

Diet & feeding

Offer sinking foods and regular animal items such as bloodworms, mussel, or shrimp. Algae and other plant matter are also consumed, so include vegetables such as cucumber or zucchini rather than using an exclusively meaty menu.

Behaviour & compatibility

Companions must match both temperament and water movement. Suitable characins, peaceful cichlids, or catfishes may work, but strong-flow setups narrow the options. Conspecific males defend space, so a group requires ample floor area and multiple potential territories.

Sexual dimorphism

Viewed from above, mature males have longer, broader heads, larger dorsal fins, and more odontodes.

Breeding

Wild spawning takes place in deep riverbank holes during the wet season; a proven home-aquarium protocol does not follow from that observation alone.

Notes

Names such as “dragon fin” or “tiger fin” describe variations in orange patterning rather than necessarily separate species. Two prominent upper-jaw teeth are characteristic, but their precise function remains uncertain. Check new specimens for signs of emaciation.
