Bristlemouth Pleco

Geographic Origin and Biotope: Wide range along the Amazon River basin, especially in the Rio Tocantins in Brazil. Found in a wide range of micro-habitats, from strong rapids among large boulders to the slow edges of amber rivers loaded with branches and wood.

Taxonomy and Morphology: Bristlemouth Pleco (L049 / Peckoltia multispinis). It is very often confused in shops with P. vittata (L015) which however differs originating from the Xingu River and presenting different banded patterns. Possesses robust odontodes on the posterior half.

Social Behavior: Generally peaceful but very stubborn in the benthic territorial sphere. A dominant specimen can hunt and "push away" rivals from a highly coveted log for days. Provide one more cave/log than the number of Loricariids.

Coloration and Sexual Dimorphism: Light color (often golden yellowish) marked by bold blackish bands on the body, with mosaic-striped fins. Males develop showy opercular odontodes (on the gills) and on the terminal part of the body (multi-spinis: many spines).

Aquarium Setup: Excellent in 100 cm (40 inches) planted and dimmed tanks or in river biotope setups with strong currents. Mopani, Mangrove, coconut tubes, and large round stones to imitate Amazonian rapids.

Diet and Feeding: Purely omnivorous. Consumes biofilm, but its diet must be mainly based on solid food rich in proteins. Excellent frozen mince, bloodworms, tubifex, and pleco tablets mixed with spinach.

Water Quality: Hardy and very long-lived fish if optimal gas exchanges and oxygenated water are guaranteed (via air stones or venturi). Sensitive to nitrites, only tolerates powerful biological filters and methodical maintenance.

Compatibility and Tankmates: One of the most suitable Peckoltia for medium-sized community tanks. Will not bother Dwarf Cichlids, Corydoras, Tetras or Angelfish. Best to avoid the presence of crabs and aggressive bottom shrimp.

Aquarium Reproduction: Easily reproduced in ceramic caves. The male takes care of parental duties by strenuously defending the cave entrance. Feed the larvae massively with brine shrimp nauplii upon free-swimming.

Risks and Diseases: Primary risks include mechanical injuries if the tank has sharp rocks, or fatal lethargy in case of prolonged excessively cold temperatures (below 22°C / 72°F).
