✂️ Usage tips

Bury the cave in the aquarium substrate so that only the transparent window is visible. Ensure sufficient substrate thickness (minimum 5 cm) for stable placement. Clean regularly by carefully removing the cave from the substrate.

💡 Tip

Ideal for cichlids and other bottom-dwelling fish that prefer a fixed hiding spot. The cave stimulates natural breeding behavior and territorial formation.
