Three Beacon Pleco

The Three Beacon Pleco is a striking and relatively uncommon member of the Leporacanthicus genus — closely related to the popular Vampire Pleco but distinguished by its namesake feature: three prominent yellowish-white spots on the dorsal region that stand out like beacons against the dark body. Also known as L091, this species from the Rio Xingu in Brazil combines dramatic visual appeal with the characteristic fanged appearance of its genus, making it a prized addition to any L-number pleco collection.

The body coloration is a deep charcoal-to-black base overlaid with scattered smaller spots and the three distinctive dorsal markings that give the species its common name. The fins carry similar spotted patterning, and the overall effect is bold and eye-catching — particularly under aquarium lighting that highlights the contrast between dark body and light spots. Like its Vampire Pleco cousin, the Three Beacon sports pronounced odontodes on its gill covers and pectoral fins.

Housing requires a minimum 55-gallon aquarium with strong filtration and moderate current to replicate the fast-flowing Rio Xingu habitat. Temperature should be maintained between 79 and 86 degrees Fahrenheit, with pH between 6.0 and 7.5. Provide rocky structures with multiple caves and crevices, as the Three Beacon is nocturnal and territorial — dedicated hiding spots are essential for reducing stress and aggression.

Like all Leporacanthicus species, the Three Beacon is carnivorous rather than algae-eating. Its diet should consist of sinking carnivore pellets, frozen bloodworms, brine shrimp, chopped shrimp, and snails. Occasional blanched vegetables provide supplemental nutrition. Feed primarily in the evening when the fish is most active.

The Three Beacon is a rewarding species for intermediate to advanced aquarists who appreciate the more predatory side of the pleco world.
