The Honeycomb Pleco is a beautiful, large suckermouth catfish that is known from both the rapids and slower flowing sections of rivers, on rocky and soft substrates. Juveniles are known to dwell in smaller streams and oxbow lakes. This species grows to a substantial size and will require a spacious, mature aquarium with soft, acidic water. Provide plenty of shady retreats amongst bogwood and sturdy rocky caves, ensuring all decor is secure as larger specimens can be a little clumsy at times. The water should be very well-filtered (adult fish produce a substantial amount of waste) and a moderate current/good level of oxygenation should be created by extra powerheads in order to simulate their natural riverine conditions. Ensure regular partial water changes are carried out to help keep nitrogenous wastes to a minimum. This species is generally peaceful, although it can be rather territorial with its own kind and similar species. More than one specimen may be kept in the same tank if it is spacious and multiple hiding places/visual barriers are provided. The Honeycomb Pleco mixes well with medium sized characins, some of the more robust Corydoras catfish species, and many rheophilic cichlids. Depending on various factors, including mood, sex, age, or surroundings, these fish are capable of quite considerable colour change. There is also a degree of geographical variance between specimens from different collection locations. H. faveolus differs from all other species of the genus Hypostomus by having a unique combination of pale blotches over a darker background in body and fins, and conspicuous keels on the head, predorsal region and lateral plates. The species name "faveolus" is derived from the Latin favus, meaning honeycomb, in reference to the reticulated colour pattern formed by the pale blotches within thin dark limits.
