Traditional coral frag holders are designed for frag tanks and made of egg crate, and if you ever put one in your display tank, they are an instant eyesore. Reef Rax has produced custom molds that simulate real live rock structures and textures at a fraction of the weight. 

Reef Rax Nano Shelf is made of a highly porous resin structure that is almost buoyant when it is first placed in your tank. The neutral buoyancy greatly helps with its ability to hold heavy frag plugs and large frags of coral. Each rack includes reef safe magnets that can support the Nano Shelf on tanks up to 1/4" thick.


Nano Shelf

Reef Rax's Nano Shelf was designed to be placed anywhere in a display tank without looking like a man-made object. it can be placed next to a corner or in the middle of your aquariums glass.



Coralline Purple Color

Reef Rax custom purple coloration resembles coralline encrusted live rock and is the perfect addition to any seasoned aquascape. Over time additional coralline algae will encrust the rack creating beautiful purple tones adding to the color depth. If you have a new aquascape with dry live rock we suggest looking into the Grey Reef Rax.

Product Questions

Are there waterproof magnets that can be purchased? I'd like to put one of these on the back wall of my AIO cube. But the magnets would be in direct contact with the water in the middle chamber.

Thanks for reaching out to us! I would recommend using the magnet below to use in an overflow/AIO application like yours. Please let us know if we can help with anything else!
