Relevant information:

Juveniles have a very different colour pattern to the adults and individuals can differ in colouration and body shape. 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. Remarks: It has now been established that this species and L333 are the same species and if they are kept together in the same tank there is a possibility of cross breeding between them. They are in fact differently marked variants (phenotypes) of the same species.
