3-Inch Mushroom Detention Center Coral Holder

A 3D printed reef accessory that keeps mushroom corals contained, easier to place, and less likely to drift where you do not want them in the tank.

• 3-inch holder: Gives reef keepers more room than a smaller mushroom cage while keeping placement controlled.
• Cleaner coral control: Helps isolate loose or wandering mushrooms while they settle, heal, or get positioned more intentionally.
• Reef-safe workflow fit: Useful for propagation, display cleanup, and controlled placement inside the tank.
• Color options available: Multiple printed colorways without changing the core function.
