Albino Blue Eyed Lemon Bristlenose Pleco Care Guide - Setup, Diet & Breeding

The Albino Blue Eyed Lemon Bristlenose Pleco is a selectively bred colour form of the common bristlenose pleco, with a warm yellow to lemon body, pinkish or pale fins and striking blue-grey eyes. Its reduced dark pigmentation gives it a noticeably brighter appearance than the wild-type fish, while its broad, flattened body and sucker-shaped mouth retain the classic bristlenose profile.

Like other members of Ancistrus, it is mainly active from dusk onwards. It spends much of its time attached to wood, rocks, glass or other surfaces, rasping at biofilm with its specialised mouth. Despite its unusual appearance, it is generally peaceful and tends to keep to itself, although mature males may dispute caves and hiding places.

Adult males develop a prominent covering of branched tentacles, or bristles, across the snout and head. Females may show a smaller number of short bristles around the edge of the snout, making the sexes relatively easy to distinguish once mature. The bristles are harmless sensory structures rather than stinging spines.

In the wild, Ancistrus cirrhosus occurs in flowing South American waters where submerged branches, leaf litter and stones create grazing surfaces and shelter. Its sucker mouth and flattened shape are well suited to clinging to surfaces in current, and its largely nocturnal lifestyle helps it forage safely among the cover.

This aquarium form is an albino colour morph of Ancistrus cirrhosus, a South American bristlenose catfish associated with the Paraná and Paraguay river systems, particularly in Brazil, Bolivia and Paraguay. The wild species inhabits freshwater streams and rivers with submerged wood, rocky surfaces and plentiful cover.

Plan on at least 80 litres for one adult, with a footprint of approximately 90 by 30 cm preferred because floor area is more important than height. Use smooth sand or fine rounded gravel, and include bogwood or driftwood, sturdy plants and caves or ceramic spawning tubes that provide secure retreats. Moderate water movement, efficient filtration and good oxygenation suit this riverine catfish, while subdued lighting and shaded areas help it feel secure. Leave some surfaces available for natural biofilm growth, but do not rely on the aquarium alone to provide enough food.

Up to around 15 cm (6 inches) in total length. Females are often slightly shorter and more compact, while large males may reach the upper end of this range.

Offer a mainly herbivorous diet based on quality algae wafers or spirulina foods, supplemented with vegetables such as courgette, cucumber, spinach and shelled peas. Driftwood should be available because grazing on its surface and ingesting small amounts of wood fibre are natural parts of the species' diet. Occasional protein-rich foods such as bloodworm or sinking catfish pellets can be given, but meat-heavy diets should not replace vegetable foods. Feed after the aquarium lights dim, when this nocturnal fish is most active.

This peaceful pleco is well suited to community aquariums with peaceful tetras, rasboras, danios, livebearers, peaceful barbs, dwarf cichlids and other calm South American community fish. It can also live with peaceful Corydoras and many smaller loaches. Avoid large predatory or relentlessly aggressive fish, fin-nippers and species that compete intensely for hiding places. Several male bristlenose plecos may become territorial, particularly in smaller aquariums, so provide separate retreats if keeping more than one.

Provide mature pairs with a narrow cave or spawning tube that the male can guard, along with clean, well-oxygenated water and a varied, plant-rich diet. The female lays adhesive eggs inside the cave, after which the male fertilises them and guards them with his body while fanning them with his fins. The eggs usually hatch in around five to seven days, and the fry become free-swimming a few days later. Offer the young fish soft vegetables, algae-based foods and suitably small fry foods once their yolk sacs have been absorbed.

Mature males develop conspicuous branched bristles over the snout and forehead, whereas females usually have fewer, shorter bristles restricted to the margins of the snout or none that are clearly visible. Males may also have a broader head and are more likely to claim and defend a cave.
