LF: Urchins Calgary

[Enigma]

If you can't turn any up from a hobbyist, and if you're willing to shop at Pisces, they have red and blue Tuxedo urchins ($30 each). I've purchased a blue one from them and will be going back for one or two more.

I can tell you that the one I purchased there eats some bryopsis. I may have two strains . . . they look a little different, and behave differently to H202 levels. It may only be eating one of the strains.
