Panaqolus albivermis ( L204 ) 2.5″-3″ WILD CAUGHT

Panaqolus albivermis (commonly known by its “L-number,” L204) is a species of small wood-eating catfish from the Loricariidae family. It is often referred to as the Flash Pleco due to its striking coloration. This species is popular among pleco enthusiasts for its attractive appearance and relatively manageable size compared to other wood-eating catfish like Panaque.

Here are some key details about Panaqolus albivermis (L204):

• Size: Panaqolus albivermis is a medium-sized pleco, reaching a maximum size of around 4.5–6 inches (11–15 cm) in length, making it more suitable for moderately sized aquariums than larger relatives.
• Coloration: The Flash Pleco has a dark brown to black base color with bright, creamy white or yellowish horizontal stripes running along its body and fins. These contrasting stripes make it a visually stunning fish.
• Distinguishing Features: The fish’s body is heavily armored, and it has a distinctive flattened shape, typical of plecos. It has a strong sucker mouth adapted for clinging to submerged surfaces and scraping wood.

• Geographic Origin: Panaqolus albivermis is native to Peru, specifically the upper Amazon River basin, where it inhabits fast-flowing, well-oxygenated rivers with lots of submerged wood and tree roots.

• Behavior: This species is relatively peaceful and can coexist with a variety of tank mates, but like many plecos, it can be territorial with other bottom-dwelling fish, particularly other plecos. It is mostly active during the evening and night.
• Tankmates: It does well with similarly peaceful species, such as small tetras, rasboras, and other non-aggressive fish. Avoid aggressive tank mates that might stress it.

• Wood Eaters: Like other members of the Panaqolus genus, Panaqolus albivermis is a xylophagous species, meaning it feeds primarily on wood. The cellulose in wood provides essential dietary fiber.
• Supplemental Feeding: In addition to driftwood, you should offer a variety of vegetable matter and commercial foods. This includes blanched vegetables (zucchini, cucumber, sweet potato) and high-quality algae wafers or spirulina-based pellets. They may also consume some protein in the form of insect larvae or shrimp, but their diet should be predominantly plant-based.

• pH: 6.0–7.5 (slightly acidic to neutral water)
• Temperature: 75–82°F (24–28°C)
• Hardness: Soft to moderately hard water (up to 12 dGH)

• Tank Size: For a group or individual, a tank of at least 30–40 gallons (114–150 liters) is recommended due to their need for space and territory. A larger tank will be necessary if keeping multiple plecos.
• Decor: The tank should be heavily decorated with plenty of driftwood, which is both a food source and hiding place for the fish. Soft wood types like bogwood or mopani are ideal. You can also add rocks and caves to provide additional hiding spots.
• Substrate: A soft substrate, such as sand or fine gravel, is recommended to avoid injury to their sensitive underbellies.
• Filtration and Oxygenation: Strong filtration is essential to keep the water clean and well-oxygenated, mimicking the fast-flowing waters of their natural habitat. A moderate to strong current is preferred, so powerheads or extra water circulation may be beneficial.

• Activity: Panaqolus albivermis is generally nocturnal and will be most active in the evening and at night. It may spend the day hiding in caves, under driftwood, or among plants.
• Social: While peaceful with tankmates, they may become territorial with other plecos or bottom-dwellers, particularly in smaller tanks. Providing ample hiding spaces helps reduce territorial aggression.

• Wood Requirement: Driftwood is essential for their health. Without access to wood, they can suffer from digestive issues. Make sure there’s always plenty available in the tank.
• Tank Mates: Due to their wood-eating habits, they produce a fair amount of waste. Therefore, a robust filtration system is essential to maintain water quality.

Panaqolus albivermis (L204), or the Flash Pleco, is a beautiful and manageable species, ideal for aquarists looking to add a striking wood-eating pleco to their community tanks. With the right tank setup and diet, they are relatively easy to care for and rewarding to keep.
