Product Information

About

Versatile Cave for Small Pets: Perfectly sized for small swimmers (fits fish up to 3cm wide). A secure aquarium hideout for shy species like Corydoras, loaches, and plecos; a playful fish tunnel for active swimmers like tetras, guppies, and bettas; and a safe shelter for invertebrates including shrimp and snails
Easy Setup: First, place the fish tank tunnel upside down in water and hold until bubbles stop—this allows water to fully fill the hollow interior. Then, gently turn it upright and release; it will sink naturally. If floating occurs, simply repeat the process to release trapped air
Fish-Friendly Design: Smooth Edges & Corner-Fit View. Every edge is carefully rounded to keep delicate fins, barbels, and scales safe. The precision 90° corner design fits snugly against tank walls and provides a clear viewing window into your fish's natural behaviors without disturbance
Premium PETG 3D Printing: About 80% lighter than ceramic, sturdy and not easily broken. BPA-free formula, lightweight yet durable, with colors that stay vibrant for years. Designed for all small aquatic pets seeking comfort, security, and fun
Flexible Use & DIY Decor: Use it directly on the substrate as a centerpiece, or partially bury it for a seamless natural look. Specially designed tree holes on the surface let you insert aquatic plants or mini decorations, turning each fish cave into your unique aquascaping masterpiece
