L191 Panaque cf. suttonorum 4 - (Panaque cf. suttonorum) — 4-5cm

Overview

Freshwater fish for sale UK enthusiasts seeking a rare and impressive armored catfish will find Panaque cf. suttonorum (L191 pleco) a captivating choice for large, well-maintained aquariums. This wood-eating loricariid originates from the Magdalena River basin in Colombia, where it inhabits fast-flowing rivers with abundant submerged driftwood. Available for sale UK in sizes from 4-12cm, the species grows into a substantial pleco—while exact maximum size is uncertain due to taxonomic ambiguity (the "cf." designation indicates uncertainty in species identification), specimens likely exceed 25cm and require planning for long-term adult size. Striking patterning, specialized dietary needs, and peaceful temperament make this an excellent show fish for aquarists prepared to provide appropriate space, water quality, and abundant driftwood. Moderate care level suits experienced fishkeepers familiar with large pleco husbandry.

Appearance

Panaque cf. suttonorum displays the bold, intricate patterning characteristic of royal plecos. The body features irregular wavy lines or vermiculations in contrasting light and dark tones—typically cream, grey, or tan against dark brown or black—creating a marbled or maze-like pattern. Juveniles often show crisper, more defined lines that may blur slightly as the fish matures. The head is broad and heavily armored, with pronounced odontodes (tooth-like projections) along the margins and gill covers, particularly prominent in males. The mouth is large and equipped with spoon-shaped teeth specialized for rasping wood. All fins display similar patterning to the body, with the dorsal fin featuring an impressive sail-like extension when raised. The ventral surface is lighter, often pale grey or cream. Body shape is robust and heavily plated, providing excellent protection from predators. Overall appearance is commanding and distinctive, making this pleco a true centerpiece fish.

Natural Habitat

This species inhabits the Magdalena River basin and associated tributaries in Colombia, where it occupies fast-flowing, well-oxygenated rivers with rocky and woody substrates. Natural habitats feature abundant submerged driftwood, fallen branches, and root systems that provide both food and shelter. Water is typically clear to moderately turbid, warm, soft to moderately hard, and slightly acidic to neutral. Current ranges from moderate to strong, especially during the wet season. The species shelters in crevices, under logs, and among rocks during the day, emerging during crepuscular and nocturnal periods to feed. In the wild, the pleco grazes continuously on aufwuchs (biofilm, algae, microorganisms) covering submerged wood, using its specialized teeth to rasp wood fibers and access the nutritious organisms and cellulose within.

Aquarium Setup

A minimum 400-litre aquarium with dimensions emphasizing length and depth over height provides appropriate space for a single adult L191 pleco. Use fine sand or smooth gravel substrate and provide substantial pieces of driftwood—multiple large, well-cured pieces are essential, as the pleco requires wood for digestion and constantly grazes on wooden surfaces. Arrange driftwood, smooth river rocks, slate, and caves to create hiding places and territories. Ensure at least one cave or enclosed retreat sized appropriately for the fish, as plecos feel most secure in tight spaces. Moderate to strong water flow replicates natural conditions and ensures high oxygenation; use powerheads or position filter outlets to create directional current. Subdued lighting suits this nocturnal species, though moderate lighting supports plant growth if desired. Robust, well-anchored plants such as Anubias and Java fern tolerate the pleco's activity, though many aquarists prefer wood-focused aquascapes for royal plecos. Ensure all decor is stable, as large plecos can dislodge poorly secured items.

Water Parameters

Maintain tropical temperatures between 24-30°C, with 26-28°C representing optimal conditions. The species tolerates the upper end of this range if water is well-oxygenated and flow is strong. pH should remain between 6.0-7.5, with slightly acidic to neutral values (6.5-7.0) ideal. Water hardness can range from soft to moderately hard, though soft to moderate hardness better replicates natural Magdalena basin conditions. Ammonia and nitrite must be undetectable, while nitrates should stay below 30 ppm through efficient biological filtration, weekly water changes of 40-50%, and powerful mechanical and chemical filtration. Panaque species are sensitive to poor water quality and require pristine conditions with high dissolved oxygen. Strong water circulation and surface agitation ensure adequate oxygen levels, especially at higher temperatures or with larger specimens.

Feeding

Panaque cf. suttonorum is primarily a wood-grazing detritivore requiring constant access to driftwood. The species rasps wood to access cellulose, lignin, and the aufwuchs (biofilm, algae, microorganisms) coating submerged wood. Supplement the diet with high-quality sinking algae wafers, spirulina tablets, and herbivore pellets designed for wood-eating plecos. Offer blanched vegetables such as zucchini, cucumber, spinach, and peas 2-3 times weekly. Occasional protein-rich foods—frozen bloodworms, brine shrimp, or quality carnivore pellets—can be offered in small amounts but should not dominate the diet. Feed in the evening to align with the species' nocturnal activity. Overfeeding protein causes digestive issues and bloating, so maintain a primarily vegetable and wood-based diet. Ensure driftwood is constantly available and replace pieces as they are consumed or degraded.

Behaviour

L191 plecos are primarily nocturnal and crepuscular, spending daylight hours hidden in caves, under driftwood, or among rocks. During evening and nighttime hours, they emerge to graze on wood, forage across substrates, and patrol the aquarium. The species is generally peaceful toward other fish but can be territorial toward conspecifics or other large plecos, especially if space or caves are limited. Males may engage in territorial displays involving raised odontodes and pushing contests, though serious injury is rare if adequate hiding places and space are provided. The pleco uses its strong sucker mouth to adhere firmly to surfaces, including glass, driftwood, and rocks, often remaining motionless for extended periods while grazing. Activity increases during water changes or when food is introduced. Overall, the species is calm, hardy, and undemanding in terms of social behavior, making it an excellent addition to peaceful community tanks with appropriate tankmates.

Tank Mates

Panaque cf. suttonorum thrives alongside peaceful community fish that occupy mid-water or upper regions. Excellent companions include tetras (Congo, diamond, bleeding heart), rasboras, rainbowfish, peaceful barbs, Corydoras catfish, and smaller plecos that do not compete for caves or wood. Avoid housing with aggressive cichlids, fin-nippers, or other large territorial plecos in undersized tanks, as competition for caves and grazing surfaces can lead to conflict. Very small fish or shrimplets may be inadvertently consumed, though the pleco is not actively predatory. The species' nocturnal habits and bottom-dwelling nature mean it rarely interacts with mid-water tankmates, reducing conflict. In appropriately sized tanks with multiple territories and ample driftwood, cohabitation with other large peaceful fish proceeds without issue.

Breeding

Breeding Panaque cf. suttonorum in home aquariums is uncommon and generally challenging. Successful spawning requires very large tanks (1000+ litres), excellent water quality, mature adults in pristine condition, and suitable caves for the male to claim and prepare as a spawning site. Males become increasingly territorial during breeding periods and may guard the cave entrance aggressively. Females deposit eggs inside the cave, after which the male assumes sole responsibility for guarding and fanning the eggs until they hatch. Fry are large and require finely powdered vegetable-based foods and access to soft wood. Rearing fry demands exceptional water quality and careful feeding. Most specimens in the trade are wild-caught, with captive breeding remaining rare among hobbyists.
