Short spine urchin knocking rockescape?

[starrynight99]

Is it likely for a short spine urchin to knock over unglued rock work? I’m talking about kgs of rock. None of my rock is glued together and I just added 2 short spine urchin to my 250gallon.

I know it’s possible but is it likely?

Yep.

I have a love/hate relationship with urchins.

Large zebra turbos will do it too.
