Coral frags left on the sandbed get buried, tip over, or grow into each other. A frag rack holds them up in the flow and light where you can watch them heal. In a nano the trick is a small, reef-safe magnetic rack that doesn't hog space.

What should you look for in frag rack for a nano reef tank?

- Reef-safe material: resin or acrylic that won't leach into the tank.
- Strong magnet: rated for your glass thickness so it won't slide.
- Nano-sized: a small shelf that fits without crowding corals.
- Good flow and light: place it where frags get moderate flow, not dead spots.
