Calico Bristlenose Pleco

The Calico Bristlenose Pleco is a selectively bred bristlenose pleco (Ancistrus sp.). Marbled orange, dark brown and black color-pattern bristlenose aquarium strain. Unlike common plecos that can exceed a foot, bristlenose varieties generally remain manageable community-aquarium catfish. They graze soft algae and biofilm but must receive their own complete diet.

Care Information

• Adult size: Approximately 4–6 inches
• Minimum tank: 20 gallons for one adult; 30+ gallons preferred for larger longfin specimens or additional bottom dwellers
• Temperature: 72–80°F
• pH: Approximately 6.5–7.5
• Water: Stable, clean and well-oxygenated, with moderate filtration and current
• Diet: Algae wafers, spirulina-rich sinking foods, blanched zucchini or green beans, plus modest occasional protein-rich foods
• Decor: Aquarium-safe driftwood, caves and smooth surfaces for grazing
• Temperament: Usually peaceful toward community fish; adult males may defend caves and territories
• Care level: Beginner-friendly when water and food needs are met

Feeding & Tank Setup

Do not depend on aquarium algae or leftover food alone. Offer targeted sinking foods, preferably when lights dim, and remove uneaten vegetables. Driftwood offers cover and natural grazing surfaces. Provide a cave for shelter, clean substrate, good circulation and sufficient swimming and bottom space. Longfin fish need décor without sharp edges that could tear their fins.

Compatible Tank Mates

Appropriate companions include peaceful tetras, rasboras, rainbowfish, Corydoras and compatible gouramis. Avoid large predators and fish that harass bottom dwellers. If keeping more than one bristlenose, provide extra caves and floor space.

Frequently Asked Questions

Is this an algae-cleaning fish? It grazes soft algae and biofilm, but still needs regular feeding and does not replace aquarium maintenance.

Does this pleco need driftwood? Driftwood is strongly recommended for grazing, shelter and enrichment; it is not a substitute for a balanced diet.

How large does it grow? Bristlenose plecos commonly reach 4–6 inches as adults.
