GOLD NUGGET LARGE DOT L081 PLECO

L081 Gold Nugget Pleco – Large Dot Variant Care Guide

Baryancistrus sp. "L081"

Overview

The L081 Gold Nugget Pleco is a visually captivating armored catfish featuring bold black coloration adorned with large, bright yellow spots and a matching golden edge on the dorsal and caudal fins. Native to fast-flowing stretches of the Rio Xingu in Brazil, this pleco requires clean, oxygen-rich water and is best suited for aquarists with intermediate experience. 

Tank Setup

• Recommended Tank Size: Minimum 55 gallons (larger for adults or communities)

• Aquascape Needs:

  • Rounded rocks and driftwood for grazing and hiding

  • Multiple shaded areas or pleco caves

  • Open swimming space mixed with cover

• Substrate: Fine gravel or sand

• Water Movement: Strong flow preferred—mimic their native river with powerheads or directional flow

• Lighting: Dim to moderate; indirect or filtered lighting is ideal

Water Conditions

• Temperature: 80–86°F (26.5–30°C) — prefers warm water

• pH Range: 6.5–7.4 — slightly acidic to neutral

• Hardness: Soft to moderately hard (2–12 dGH)

• Oxygen Level: High — supplement with air stones or venturi-powered filters

• Maintenance: Weekly 30–50% water changes with attention to nitrate control

They are extremely sensitive to deteriorating water quality. Pristine conditions are a must.

Behavior and Compatibility

• Temperament: Semi-territorial but generally peaceful

• Behavior: Primarily nocturnal but may graze during dimly lit hours

• Compatibility:

  • Best kept with mid-to-top dwelling fish (tetras, hatchetfish, etc.)

  • Avoid housing with other bottom dwellers competing for the same space (especially other plecos or aggressive cichlids)

Provide multiple caves or resting spots if keeping with similar species.

Feeding

• Diet Type: Omnivore with a preference for protein and biofilm

• Primary Foods:

  • High-quality sinking pellets (meat- and algae-based)

  • Blanched vegetables (zucchini, spinach, sweet potato)

  • Frozen foods (bloodworms, mysis shrimp)

  • Algae wafers supplemented with fresh driftwood for grazing

While they enjoy some algae and plant matter, protein plays a vital role in their long-term health. Feed after lights out to align with their natural behavior.

Breeding

• Reproduction in Captivity: Rare and difficult due to their sensitivity to water conditions and breeding cues

• Setup Requirements:

  • Simulated seasonal flow changes and temperature drops

  • Deep rock crevices or tight-fitting caves

• Spawning Behavior: Males guard the eggs until hatching

• Fry Challenges: Slow growth rate; fry require soft water and frequent feedings of biofilm or powdered fry food

Captive breeding is best left to experienced breeders with precise control over tank parameters.

Health Concerns

• Most Common Issues:

  • Skin and fin damage from poor tankmates or rough décor

  • Bloating or internal infections from poor-quality or unvaried diet

  • Suffers quickly from high nitrate or low oxygen conditions

Preventive care includes regular tank cleaning, varied diet, and avoiding overcrowded tanks.

Quick Facts
