Water parameters
Overview
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
- 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
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
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.
