L236 Super Yellow Hypancistrus Pleco

L236 Super Yellow Hypancistrus Pleco | A Rare and Coveted Collector's Pleco

The L236 Super Yellow Hypancistrus Pleco (Hypancistrus sp.) is one of the most visually stunning and sought-after plecos in the freshwater aquarium hobby. A selectively developed colour variant of the L236 lineage — the same lineage as the legendary Zebra Pleco (L046) — the Super Yellow stands out with an intense, vibrant yellow base colouration contrasted against intricate black patterning that shifts and varies between individual fish. Also known in the trade as the Cracked Zebra Pleco, every single specimen displays unique markings, making each one a genuinely one-of-a-kind showpiece.

Originating from the fast-flowing, oxygen-rich waters of the Xingu River system in Brazil, the L236 Super Yellow is a fish for the serious aquarist — demanding in its requirements but rewarding those who meet them with a breathtaking, rarely seen display fish that will be the centrepiece of any high-end freshwater setup.

L236 Super Yellow Pleco Tank Setup

A rocky, cave-rich aquarium with strong water flow and excellent oxygenation is essential for this species — replicating the fast-moving, well-oxygenated Xingu River habitat it originates from. Provide multiple caves, ceramic tubes, and tight hiding spots — these are nocturnal fish that spend most of the day sheltered and become active after lights out. Smooth gravel or fine sand substrate protects their delicate barbels, and driftwood adds additional structure and grazing surface. Strong, efficient filtration is non-negotiable — pristine water quality is critical to keeping their vivid yellow colouration intense and their health robust.

Feeding Your L236 Super Yellow Pleco

Primarily carnivorous — unlike many common pleco species, Hypancistrus are not heavy algae eaters and require a protein-rich, varied diet to thrive. Offer high quality sinking carnivore pellets and insect meal granules as a staple, supplemented generously with frozen or live foods such as bloodworm, brine shrimp, and blackworms. Occasional blanched vegetables such as zucchini and cucumber can be offered as a supplement. Feed after lights out for best results, as these are strongly nocturnal feeders.

Breeding L236 Super Yellow Plecos

Cave spawners that can be bred in the home aquarium with the right conditions. The male guards the eggs and fry inside a tight cave until they are free-swimming. Slightly elevated temperatures, pristine water quality, and cool partial water changes are reliable breeding triggers. Males can become territorial around spawning sites — provide one cave per individual to reduce conflict.

L236 Super Yellow Pleco Tank Mates

• Small to medium peaceful community fish — tetras, rasboras, and danios
• Dwarf cichlids such as Apistogramma and Rams
• Peaceful mid and upper water fish
• Other Hypancistrus with caution — males can be territorial with one another; provide ample caves and visual barriers
• Shrimp and snails — generally safe
• Avoid large, aggressive cichlids and boisterous bottom dwellers that will compete for caves and territory
