Breeding Hypancistrus furunculus (L260)

Breeding the L260 queen arabesque Hypancistrus furunculus: cave spawning with male brood care following the documented Hypancistrus pattern, plus sexing and setup.

Overview

Hypancistrus furunculus (L260), the queen arabesque pleco, is a small loricariid endemic to the Orinoco River in Venezuela, described by Armbruster, Lujan and Taphorn in 2007. FishBase lists it as a freshwater, demersal species rated Least Concern. Detailed spawning reports for this species are scarce, so the account below follows the documented breeding biology of the genus Hypancistrus, including its close relative H. inspector.

Sexing

In Hypancistrus, adult males develop more odontodes on the leading pectoral-fin rays and the interopercular region than females, and males are usually more slender when viewed from above.

Breeding Setup

Hypancistrus species occupy bedrock and crevices in slow to moderately flowing water and spawn in caves, so provide narrow caves or tubes. Strong water movement and high dissolved oxygen, as recommended for the genus, are advisable.

Spawning Behavior & Trigger

As cave spawners, the female deposits a clutch inside a narrow cave and the male is responsible for brood care, remaining to tend and defend the eggs.

Egg & Fry Care

The male guards the clutch within the cave through hatching, and the fry stay in or near the cave until their yolk reserves deplete before they become free-swimming. The fry accept small meaty foods once feeding, in keeping with the carnivorous-to-omnivorous diet of the genus.

Common Challenges

Hypancistrus species hybridise readily, so a single species should be kept in the breeding tank. Given the rocky-river origin, clean and well-oxygenated water with strong flow must be maintained throughout brood care.
