L340 Mega Clown Pleco (Hypancistrus sp. L340) Bred in SA

The L340 Mega Clown Pleco is a striking species of pleco admired for its vibrant black and yellow or orange striped pattern, reminiscent of a clown’s costume. Native to the Rio Negro and its tributaries in the Amazon Basin, this pleco is a relatively small and peaceful species, making it ideal for smaller aquariums. Its bold markings and hardy nature have made it a favorite among aquarists seeking a unique bottom-dweller.

Natural Habitat

In the wild, the L340 Mega Clown Pleco inhabits slow-moving, tannin-rich blackwater rivers with soft, acidic water. These areas are filled with submerged driftwood, rocks, and leaf litter, which provide shelter and grazing opportunities.

Aquarium Care

Tank Requirements

• Minimum Tank Size: 60 liters for a single individual; larger tanks for groups.
• Water Temperature: 26–30°C.
• pH Range: 6.0–7.5.
• Water Hardness: 2–12 dGH (soft to moderately hard water).
• Filtration: Moderate flow with efficient biological and mechanical filtration to maintain water quality.

Aquascaping

• Use fine sand or smooth gravel as substrate.
• Include plenty of driftwood and caves for hiding and territorial purposes.
• Add smooth rocks and decorations to replicate their natural environment.
• Live plants such as Java Fern and Anubias can be added but are not essential.
• Moderate to subdued lighting is ideal, as these plecos prefer dim conditions.

Tank Mates

• Suitable tank mates include peaceful, small to medium-sized species like tetras, rasboras, and dwarf cichlids.
• Avoid aggressive or territorial species that may harass the pleco.

Feeding

The L340 Mega Clown Pleco is an omnivore with a preference for meaty foods:

• Staple Foods: High-quality sinking pellets or wafers.
• Protein: Live or frozen foods like bloodworms, brine shrimp, and blackworms.
• Vegetable Matter: Occasional blanched vegetables such as zucchini, cucumber, or spinach.
  Feed once or twice daily, and ensure food reaches the bottom for easy access.

Breeding

Breeding the L340 Mega Clown Pleco is achievable with specific conditions and careful preparation.

Sexing

• Males: Typically have larger odontodes (spines) on their cheeks and pectoral fins.
• Females: Rounder body, especially when carrying eggs, and less pronounced odontodes.

Breeding Tank Setup

• Use a separate breeding tank of at least 60 liters.
• Maintain optimal breeding conditions:
  • Temperature: 28–30°C.
  • pH: 6.0–6.5.
  • Soft Water: Ensure water is soft to replicate their natural environment.
• Provide plenty of caves or tubes as spawning sites.

Spawning Process

1. The male selects a cave and defends it, enticing the female to spawn inside.
2. After spawning, the male guards the eggs, fanning them to ensure proper oxygenation.
3. Eggs hatch in 4–7 days, and the fry become free-swimming after another 7–10 days.

Fry Care

• Feed fry infusoria or finely crushed spirulina-based flakes initially.
• Gradually transition to baby brine shrimp and sinking pellets as they grow.

Key Notes

• Behavior: The L340 Mega Clown Pleco is peaceful and nocturnal but may show territorial behavior toward other bottom-dwellers.
• Maintenance: Regular water changes and excellent filtration are essential for their health and vibrant coloration.
• Health: Watch for stress-related diseases such as ich or bacterial infections, which can occur in poor water conditions.

The L340 Mega Clown Pleco is a visually stunning and manageable species that thrives in well-maintained aquariums. Its unique patterning, peaceful nature, and compatibility with community fish make it a captivating addition for aquarists of all experience levels.
