Tuxedo urchin crunches mangrove roots

[itelshot]

It's the 2nd time i noticed that my mangrove roots were chewed. It could be only one monster- tuxedo urchin.
I don't know any other CUC that will control algae as good, also i don't wanna place mangroves not in the display (what else purpose instead of decoration could it be).
Is it possible if i find another urchin and it won't eat roots? And... i will be glad to listen you exp in urchins and similar mangrove situations.

very likely to be the urchin, and its unlikely that if you replace it, the next wouldn't do the same.
