L027c Araguaia Gold Line Thunder Royal Pleco (Panaque armbrusteri)
The L027c Araguaia Gold Line Thunder Royal Pleco is a rare and highly coveted variant of the Royal Pleco, distinguished by its bold golden striping contrasted against a dark, armored body. Native to the Araguaia River basin in Brazil, this species combines the rugged, prehistoric look of Panaque plecos with a unique, high-contrast “thunder line” pattern that intensifies with age. A true collector’s fish, this pleco is ideal for serious hobbyists looking to add a standout bottom-dweller to a large display aquarium.
Diet
Unlike most predatory catfish, this species is primarily herbivorous/wood-grazing:
- Driftwood (essential — aids digestion)
- Algae wafers and sinking veggie pellets
- Fresh vegetables (zucchini, cucumber, sweet potato)
- Occasional protein (shrimp or pellets) in moderation
A constant supply of driftwood is critical for long-term health.
Tank Requirements
- Minimum Tank Size: 125–180 gallons
- Water Type: Freshwater
- Temperature: 75–82°F
- pH: 6.0–7.5
- Setup: Heavy driftwood presence, strong filtration, moderate flow; provide caves or shaded hiding areas
This species produces a lot of waste due to wood consumption, so powerful filtration is a must.
Max Size
- Maximum Adult Size: 16–20 inches
Tank Mates
Generally peaceful but territorial with other bottom dwellers:
- Compatible: Arowanas, datnoids, large cichlids, stingrays, and other mid-to-top dwelling species
- Use caution: With other plecos or similar bottom fish (may become territorial)
- Avoid: Very small or delicate species
Temperament
Peaceful overall, but can be territorial around its hiding spots, especially as it matures.
