Blood-red Tiger Pleco Care Guide - Aquarium Setup, Diet & Breeding

The Blood-red Tiger Pleco is a striking small loricariid with a broad, armoured body, a flattened underside and a powerful sucker mouth. Its base colour ranges from deep brown to near-black, overlaid with warm red, orange or rust-coloured tiger-like markings that become especially attractive under subdued aquarium lighting.

Like other Panaqolus, it is adapted for clinging to wood and rock in moving water. Its mouth and rasping teeth allow it to graze biofilm and soften woody surfaces, while its armoured plates provide protection among submerged branches and rough riverbed debris.

This pleco is generally peaceful with unrelated community fish, although it may defend a favourite cave or feeding area from other bottom-dwellers. It is usually most active after dusk, when it emerges to explore, graze and search for food.

In nature, Blood-red Tiger Plecos inhabit clear to lightly stained tributaries and rocky margins of the Amazon basin. Their attractive pattern, manageable adult size and interesting nocturnal behaviour have made them popular among aquarists who enjoy specialised plecos.

The Blood-red Tiger Pleco, Panaqolus claustellifer, is native to the Rio Tapajós basin in Pará, Brazil, in the South American Amazon region. It comes from warm, highly oxygenated waterways with rocky areas, submerged wood and flowing water.

A single Blood-red Tiger Pleco should have at least 120 litres, with a footprint of approximately 90 x 40 cm; a larger aquarium is preferable for groups or mixed bottom-dweller communities. Use efficient filtration and strong oxygenation, while avoiding stagnant areas. Provide several caves, shaded retreats and substantial pieces of smooth driftwood, along with rounded stones and hardy plants attached to the decor. A sand or fine, smooth-gravel substrate is safest for the underside and barbels.

Up to about 12 cm (4.7 in) in standard length. Females are often slightly shorter and fuller-bodied, while mature males may appear longer and more robust.

Offer a varied diet built around algae wafers, spirulina-based tablets, sinking vegetable foods and blanched courgette, cucumber, spinach or green beans. Driftwood should always be available because wood is an important part of the natural diet of Panaqolus. Supplement occasionally with quality sinking pellets and modest portions of protein-rich foods such as prawns or bloodworms, particularly for growing fish, while removing uneaten vegetables promptly.

Blood-red Tiger Plecos are suitable for peaceful community aquariums. Good companions include small tetras, pencilfish, peaceful rasboras, hatchetfish, small barbs, peaceful dwarf cichlids and other non-aggressive South American community fish. Avoid large predatory or boisterous species, fin-nippers and strongly territorial bottom-dwellers. Keeping multiple plecos requires enough caves and territory, and similarly shaped or closely related plecos may compete with one another.

Blood-red Tiger Plecos are cave spawners. Provide several snug ceramic or slate caves, ideally with entrances only slightly larger than the fish. After courtship, the female deposits a batch of adhesive eggs inside a cave, while the male guards and fans them until they hatch. The fry can be raised on soft vegetables, algae-based foods and finely powdered sinking foods, with driftwood available from the beginning.

Mature males usually develop more obvious odontodes or bristle-like projections on the cheeks and along the pectoral-fin spines, and they often have a broader, more muscular head. Females tend to have a rounder abdomen and a smoother head, with fewer pronounced odontodes.
