Relevant Information:

Named by Armbruster, Lujan & Taphorn in their paper of 2007as Hypancistrus furunculus (L199) along with three other species, H. contradens, (L201 which was first thought to be H. inspector and is now a different species), H. lunaorum (L339) and H. debilittera (L129). Hypancistrus furunculus can be distinguished from H. contradens, H. inspector, and H. lunaorum by having oblique bars on the anterior part of the body and horizontal bands in the dorsal fin (vs. white spots); from H. debilittera by having complete bands in the dorsal fin (vs. incomplete bands), dark E on snout distinct (vs. absent or indistinct), anterior dark bars complete, straight, and distinct (vs. incomplete, vermiculate, and/or indistinct) and by having the light bands in the caudal about equal in width with dark bands (vs. light bands less than half the width of the dark bands); from H. zebra by having a tan background color (vs. almost white), by having only one oblique stripe on the body and dorsal saddles posteriorly (vs. sides completely with oblique stripes). Similar to the Panaque/Panaqolus and Peckoltia genera but have fewer and larger teeth in the lower and upper jaw. Sexual differences: Males posses a broader and longer head and odontodes on the posterior part of the body, behind the gill covers and on the pectoral fin spines. The latter two are a lot shorter in the females. Aquarium Care: No problem with keeping in groups but only one Hypancistrus species to a tank as there has been reports of hybridisation. Diet: Omnivores, juveniles are keen on vegetable foods whereas adults are less so. Frozen foods such as brine shrimp, mosquito larvae and mussels as well as tablet foods.
