Cholla Driftwood Tunnel for Shrimp and Fry, 6-Inch Natural Aquarium Hideaway for Planted Freshwater Tanks

Give freshwater shrimp and small fry a sheltered place to retreat, feed and settle into their daily routine. This cholla driftwood tunnel has a hollow center and perforated walls that provide cover inside a planted aquarium.

Its porous honeycomb structure encourages biofilm growth, creating a natural feeding surface for shrimp and young fry. The textured exterior also gives mosses, Anubias and Bucephalandra an easy place to attach as the tunnel becomes part of the aquascape.

Key Features

• The hollow center and perforated walls offer molting shrimp and small fish a protected retreat from larger tank mates.
• Its porous surface stimulates nutrient-rich biofilm growth, giving shrimp and fry a naturally occurring food source to graze.
• Mosses, Anubias and Bucephalandra attach readily to the textured wood, allowing the tunnel to develop into a planted sunken-log feature.
• Released tannins can slightly lower the aquarium's pH, supporting conditions that resemble the blackwater habitats of many tropical species.
• Natural variation makes every piece visually distinct while maintaining the same practical tunnel form for freshwater aquascapes.

Specifications

• Material: Dried husk of the cholla cactus.
• Dimensions: 6 inches long and approximately 1.5–2 inches in diameter.
• Pack options: Single or 3 Pack.
• Compatibility: Best suited to freshwater shrimp or small fry.
• Preparation: Rinse thoroughly before placing in the aquarium.
• Sinking: Soak for 24–48 hours or boil for 20 minutes to help the dry wood become waterlogged.
• Safety: Larger, curious fish and other fauna may become caught in the tunnel's small crevices.

Once prepared and waterlogged, settle the tunnel into your hardscape as a useful refuge, biofilm surface and plant anchor for a shrimp-focused freshwater aquarium.
