2-Inch Mushroom Detention Center Coral Holder

A 3D printed aquarium holder designed to keep mushroom corals contained, easier to place, and less likely to drift where you do not want them in the tank.

• 2-inch footprint: Better suited to smaller reef layouts and tighter placement zones.
• Cleaner coral handling: Helps isolate and display loose mushrooms more neatly than letting them wander or disappear into the rockwork.
• Reef-use accessory: Built for hobbyists trying to position, protect, or observe mushroom corals more easily.
• Multiple color options: Available in several colorways for different tank setups and preferences.

A practical little reef accessory for hobbyists who want better control over where mushroom corals sit and how they present in the tank.
