Over the years I've had quite a few urchins. 3 Tuxedos, 2 Pincushions, etc... But all of them couldn't survive more than a year except this guy. The thing is, 99% of the time he always stays on the glass and NEVER bothers any coral frags or knock them out, unlike the pincushion and tuxedo which was super annoying to me. I was curious why this guy is different/has such "good manner" ?
Also he looks like a longspine but I think they look a bit different? What kind is this guy?
2inch in diameter
