L027b XINGU PANAQUE AMBRUSTERI

L027b Xingu Panaque – Care Guide

Panaque cf. armbrusteri “Xingu”
Common Name: Xingu Royal Panaque

Overview

The L027b Xingu Panaque is a striking, large-bodied pleco known for its deep blue-gray base color and bold golden streaks across the head and body. Originating from Brazil’s Rio Xingu, this armored catfish combines powerful wood-eating jaws with a surprisingly calm demeanor, making it a prized addition to large aquariums.

Natural Habitat

Found in rocky, fast-moving stretches of the Rio Xingu, the Xingu Panaque thrives in oxygen-rich water with submerged wood, crevices, and turbulent flow. Its digestive system is specialized for consuming wood (xylophagy), a rare trait among aquarium fish.

Tank Setup

• Minimum Tank Size: 125 gallons for adults (juveniles can be started in 75+ gallons)

• Tank Style: River-style or Amazon biotope

• Décor:

  • Ample driftwood for feeding and shelter

  • Smooth boulders and rock caves

  • Sandy or fine gravel substrate

• Flow and Oxygen: High flow with additional aeration (powerheads, wave makers, air stones)

• Lighting: Low to moderate; prefers dim or shaded areas

This species requires space, stability, and plenty of wood to chew. A secure lid is also recommended, as they are strong enough to move décor and potentially dislodge tank covers.

Water Parameters

• Temperature: 80–86°F (27–30°C)

• pH: 6.2–7.4 (slightly acidic to neutral)

• Hardness: 2–10 dGH

• Water Quality:

  • Low nitrates

  • Zero ammonia/nitrite

  • Weekly 30–50% water changes essential

This fish is sensitive to poor water conditions and requires steady parameters, especially at larger sizes.

Diet

• Primary Diet: Wood and plant-based (xylophagous)

• Staples:

  • A constant supply of aged driftwood (essential for digestion)

  • Algae wafers and spirulina-based pellets

  • Fresh vegetables (zucchini, cucumber, sweet potato, green beans)

• Supplements:

  • Occasional protein-rich foods like Repashy "Soilent Green" or “Morning Wood” blends

  • Avoid high-protein meaty foods—can cause digestive issues

This pleco digests wood as a primary food source, so driftwood is not optional—it’s vital.

Behavior and Compatibility

• Temperament: Generally peaceful, but territorial with other large plecos

• Activity Level: Active at night or in dim light; reclusive by day

• Tankmates:

  • Peaceful cichlids (Geophagus, Severums)

  • Silver dollars, tetras, and other calm species

  • Avoid aggressive bottom dwellers or fin-nippers

Give each Xingu Panaque its own territory and hiding spaces to reduce aggression.

Breeding

• Reproduction in Captivity: Extremely rare

• Challenges:

  • Requires large tanks with natural seasonal cues

  • No confirmed successful large-scale captive breeding at hobbyist level

• Observation: Males may guard caves, but conditions for spawning are difficult to replicate

This species remains mostly wild-collected due to breeding complexity.

Health and Disease

• Prone to:

  • Bloat from poor diet or overfeeding protein

  • Stress from poor water flow or low oxygen

  • Digestive issues if no wood is provided

• Preventative Care:

  • Maintain oxygen levels and consistent feeding

  • Avoid sharp rocks or aggressive tankmates

  • Quarantine new arrivals

Summary

The L027b Xingu Panaque is more than just a showpiece—it’s a living example of evolutionary specialization. With proper care, this pleco becomes a centerpiece in any large tropical setup. Keep it warm, well-oxygenated, and well-fed with wood, and it will thrive for years.
