When partially buried, it blends seamlessly with dark gravel and aquascaping plants, adding depth and visual interest to freshwater tanks. Requires aquarium tank length ≥9.84 inches. Ideal for watching shrimp and small bottom dwellers explore underground spaces.\u003c\/li\u003e\n\u003cli\u003eSide-Flow Water Channel \u0026amp; Blockable Small Apertures: The partial cutaway design creates a side flow passage to reduce stagnant dead zones inside the cave. Extra small side openings can be easily blocked off using substrate, preventing fish or shrimp from getting trapped. Shrimp and micro crabs can freely use the accessible openings for crawling in and out.\u003c\/li\u003e\n\u003cli\u003e1.77in Wide Top Entrances, Designed for Small Aquatic Creatures: Two large top openings of 1.77\" (45mm) diameter create a low-stress shelter space.

Not intended for full-size large fish.\u003c\/li\u003e\n\u003cli\u003ePre-Smoothed Aquarium-Safe 3D Printed Rock Texture: Made with aquarium-safe 3D printed material with layered sedimentary rock finish to blend naturally with gravel and aquatic plants.
