Product Introduction: This is a 3D-printed, bio-inspired hideaway designed specifically for benthic fish and small ornamental fish. The model features a unique stacked-rock design, with an intricate network of maze-like tunnels and concealed spaces inside. It effectively reduces fish stress in unfamiliar environments, providing shrimp and fish with safe resting areas, breeding grounds, and shelters from external disturbances—making it a practical aquascaping accessory that enhances the sense of security in the aquarium ecosystem and adds depth to the artificial landscape.

Design Highlights:

• Biomimetic Stacked Structure: The exterior mimics the irregular forms of natural weathered rock or miniature caves, with a realistic rock-textured surface that blends seamlessly into various aquascape styles, including planted tanks and biotope setups.
• Three-Dimensional Porous Design: The model incorporates numerous irregular openings and passageways throughout its interior and along its sides, allowing fish and shrimp to move freely while providing ample visual cover to minimize the likelihood of startling them.
• Multilevel Spatial Configuration: The tiered design creates a three-dimensional activity zone: the lower, darker, and more secluded level is ideal for shy species to hide, while the upper level features larger openings that make it easier for fish and shrimp to peek out and feed, enhancing the overall aesthetic appeal.
• Safe Materials and Construction: Made from eco-friendly, aquarium-grade filament via one-piece printing, with a smooth, polished surface free of sharp edges, ensuring that fish and shrimp won’t get scratched during swimming or hiding.

Technical Specifications:

• Applicable Species: Small tropical fish (such as tetras and guppies), benthic fish (such as Corydoras and plecos), ornamental shrimp, and small crabs.
• Product Dimensions: Recommended dimensions (L × W × H): 8 cm × 8 cm × 12 cm (actual printed dimensions may vary).
• Installation Method: Simply place the item on the aquarium substrate or among driftwood and rocks; it’s ready for use once submerged.
• Recommended Filament: High-toughness PLA/PETG, which offers excellent water resistance and corrosion protection.

Application Scenarios:

• In newly set up aquariums, it helps timid fish acclimate quickly and develop a sense of security.
• It serves as a spawning and breeding shelter for territorial and aggressive cichlids.
• In planted tanks or aquaria decorated with driftwood, it fills the visual void at the bottom, enhancing the sense of depth.
• It provides absolute refuge for small ornamental shrimp, such as crystal shrimp, during molting.
