Honeycomb Pleco L037 Care Guide - Aquarium Setup, Diet & Breeding

The Honeycomb Pleco, Hypostomus faveolus L037, is a robust armoured catfish named for the network of dark markings that gives its body a honeycomb-like appearance. Its base colour ranges from tan and golden brown to olive, with darker reticulated patterning across the head, body and fins. Like other loricariids, it has bony plates and a powerful sucker-shaped mouth adapted for clinging to hard surfaces.

This is generally a peaceful, slow-moving fish that spends much of the day resting on the substrate, beneath wood or in other shaded areas. It is most active from dusk through the night, when it explores surfaces for food. Adult individuals can become territorial around favourite caves and feeding sites, particularly when space is limited.

In the wild, Honeycomb Plecos inhabit warm South American rivers and tributaries where flowing water, submerged branches, stones and patches of algae provide both food and shelter. Their flattened profile and armoured body help them cope with currents and with life close to the riverbed.

Although often sold as an algae-eating pleco, this species grows considerably larger than many of the small ornamental bristlenose-type catfish. It is a long-lived, impressive community fish for spacious aquariums, provided its adult size and need for substantial bottom area are taken seriously.

Honeycomb Plecos are native to Brazil in the Tocantins–Araguaia river system of South America. They occur in warm freshwater habitats associated with river channels, rocky margins and submerged cover.

A single adult Honeycomb Pleco should have at least 300 litres, with a larger aquarium strongly preferred as the fish matures. Aim for a footprint of about 120 × 45 cm or greater rather than relying on height alone, since floor space and swimming length are important. Use smooth sand or fine rounded gravel, robust driftwood, sturdy rocks and several caves or shaded retreats; all decor must be stable because this powerful fish can move objects while foraging. Good filtration, strong oxygenation and regular maintenance are essential, with open areas left for nighttime exploration.

Up to approximately 30 cm (12 in) in total length. Females may become slightly deeper-bodied, while males are often a little more elongated and heavily built around the head and fins.

Offer a varied diet built around sinking algae wafers, spirulina-based foods and vegetables such as courgette, cucumber, spinach and shelled peas. They also accept quality sinking catfish pellets and occasional meaty foods such as bloodworm or brine shrimp, especially when young, but animal protein should not dominate the diet. Driftwood and naturally growing algae or aufwuchs are useful supplementary grazing surfaces, while uneaten vegetables should be removed promptly.

Honeycomb Plecos are usually suitable with peaceful and moderately robust community fish, including larger tetras, peaceful barbs, rainbowfish, rasboras, larger livebearers, peaceful South American cichlids and other non-aggressive catfish. They should not be housed with highly aggressive cichlids, fin-nipping species or delicate fish that may be disturbed by a large nocturnal bottom dweller. Avoid overcrowding the substrate with several large plecos, as mature males may defend caves and feeding areas.

Honeycomb Plecos are cave spawners, with the male usually selecting and guarding a narrow cave while the female deposits a batch of adhesive eggs. The male tends the eggs and protects the fry until they become free-swimming. Successful breeding in aquaria is uncommon and generally requires mature, well-conditioned adults, excellent water quality, suitable spawning caves and a large, stable aquarium with strong oxygenation.

Mature males commonly develop more pronounced bristles or odontodes along the pectoral spines and body, together with a broader, more angular head. Females are typically fuller through the abdomen and have a rounder head profile, although the differences can be subtle outside breeding condition.
