I thought this was interesting and worth sharing...
A while back I picked up a long spine urchin that decided to start lawn mowing my acropora so it got demoted to sump duty. Down there I have a little Tunze Eco chic light that illuminates a little refugium, so lots of coralline algae grows, including on the power cord to my UV's Sicce Syncra pump.
I noticed the urchin seems to have chewed through outermost insulation of the power cord!
