Urchin proof frag rack

[Bpb]

Need help. I'm about to restock on acros soon and have a dilemma. Last time I ran a frag rack in the display, my pincushion urchin was a problem. It seems like no matter where I put the rack, the urchin will eventually roam over it and collect all the frags on it and carry them away.

The clownfish hates the rack as well and is able to knock it down but eventually stops and accepts it. The urchin though is an issue.

Getting rid of the urchin isn't in the plans. They're just too efficient of cleaners. My single urchin keeps the rocks spotless and has eradicated both bubble algae and red turf. He's earned his tenure. Just need a rack that can stand up or an idea of how to anchor them down. Any ideas?

I have the same problem. I have 4 urchins in my tank.

What about a drop of superglue on the underside of the lip of frag plug? You should be able to rip it out with damaging frag rack too bad. Another option could be to glue something to bottom of the frag plug to act as a"lock" (putty?, rubble rock?)

You could suspend the frag rack in the middle of the water column. Some hard tubing attached to the rack and connect to some egg crate or pvc above the tank.

I see there is a frag rack out with silicone "fingers" in each plug hole to kind of "grab" them and hold on a bit. I am skeptical if they can hold up to the urchin

Dab of glue may do the trick though that way I can break them off for weekly dipping

This is a spectacular idea actually. My rock scape would allow for it too

This would be the only way. I had one as well. He would remove frags from rocks that were glued down.
