I have a pin cushion urchin and it keeps knocking all of my frag plugs off my rocks. Should I get rid of the urchin or find a better way to secure the plugs? I only have an AIO so I don’t want to throw him in the back.
Urchin keeps knocking things over.

I always think that I would like an urchin for algae but then I think about your situation and what so many folks have experienced and I have decided to leave them for some one else. My snails and clownfish do enough damage already. I had to reglue a couple of things again today.
How do you currently secure the frag plugs to your rocks?

Gotta love urchins to keep them. They're absolute bulldozers at adult size which they reach large size quite quickly (other than tuxedos)
Brs extra thick super glue
I have two pincushion urchins, and I’ve found this method to be best for me.
I clip the stem of the plug, then glue > epoxy > glue to the rock
It’s demonstrated in this video at the 3:10 mark:
Nah don't get rid of it, I second breaking the plug stem. You can use a Dremel disc if you wanna do it fast. Lots of glue like loc-tite gel control. Just a future tip in case it happens to you too: My short spine urchin is strong enough to move some rock work. IF it gets to that point for you too you can buy some carbon fiber rods on amazon, they are mainly used by RC Plane hobbyists. If yours starts knocking over rocks you can cut the rods and glue them into your rock work at the spots rocks tend to tip.
Hell yeah guys thank You. I’m going to try using glue + epoxy to secure them down. Definitely didn’t wanna get rid of the urchin because I know they’re awesome algae eaters.
Glue and epoxy the frags down or glue and epoxy the urchin down.
You might have to reglue a few frags here and there but eventually you'll get them to stay put.

Not gonna lie ... I do this with my Singapore Angel. When I put something new in the tank I wait for him to come up and try to nip it. Then I tap on the glass until he looks at me. We do this up to half a dozen times, he gets the hint, we all move on with our lives.
