Overview

October 16, 2026 · Suggest an edit

The bluespotted pleco is a species endemic to the Xingu basin, recognized by the countless tiny light spots on its dark body. In older sources it appears under the name Oligancistrus punctatissimus. Its standard length is around 10–11 cm; including the tail it reaches 12 cm.

Like other L-number species from the Xingu, it needs warm, clean and oxygen-rich water. It is not found very often in the trade. Its flat body lets it cling tightly to stones in the current; it spends the day in rock crevices.

Tank Setup

October 16, 2026 · Suggest an edit
  • At least 120 liters for one or two fish.
  • Strong flow and aeration; flat stones, rock piles and caves.
  • 27–29°C, a 30% water change every week.

Diet

October 16, 2026 · Suggest an edit

Omnivorous. Vegetable and protein-rich sinking tablets, spirulina, bloodworms, mysis and brine shrimp can be given in rotation. Feed in the evening. It cannot live on the algae in the aquarium alone.

Behavior and Compatibility

October 16, 2026 · Suggest an edit

Peaceful and nocturnal. Males of its own kind may squabble over caves; it leaves other fish alone.

Good companions: Calm species that like warm water: cardinal and rummy-nose tetras, dwarf cichlids, sterbai corydoras.

Avoid: Large territorial plecos, aggressive cichlids, coldwater fish.
