Natural Looking Frag Racks from Reef Rax

  • Blends Seamlessly Into Your Aquascape
  • Add More Coral When You're Out of Room
  • Made from Reef-Safe Resin


Make your prized coral frags stand out with the Large Corner Frag Rack. Reef Rax Frag Racks mount to your aquarium's glass or acrylic with their strong reef-safe magnets.

Traditional coral frag holders are designed for frag tanks and often made of egg crate. They're often seen as major eyesores, especially if you're using it in your display tank. Reef Rax has produced custom molds that simulate real live rock structures and textures that are not only functional, but look great.

Reef Rax Frag Racks are made with 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. Multiple size and shape options are available to fit your specific needs.


Three Color Options Available:

Purple Coralline





Frag Hole Size - 0.45" diameter

Number of Holes - 25

Max Tank Thickness - 3/4"

Hey there,
Thank you for reaching out to us. Hi Zack. I didn't even know we had that corner frag holder like that. The diminutions are 8 x 6.5". I might need to get one. Perfect for my tank. Please let me know if you need anything further.

I understand the magnet on the frag rack is encased and reef-safe, but what about the magnet on the other side of the glass? I'd like to place the magnet underwater inside my overflow box. Is that magnet reef safe and ok to submerge?

Hello, all magnets are coated in ceramic so they should be resistant to salt water. However I do recommend checking the magnet periodically for corrosion and remove it if you find any.
