Aquarium Tetrapod with Top Hole

This 3D-printable tetrapod is designed as a decorative and functional structure for aquariums. It provides a safe and cozy hiding spot for small fish and shrimp. The model includes a bottom cavity to add sand or small stones for weight, preventing it from floating. Recommended to print with PETG for water resistance and long-term durability. Smooth the surface for better safety before placing it in your tank.
