I don't know what it is, but I saw some nearly identical wild ones in Hawaii, and they were over 6" across, including the spines. Big things.

What?
Yes they are about 4 inches across right now and still growing i'm sure, had the 2 biggest for about 8 months, about 3 months in I magically acquired 13 more lol, I think they were doing something naughty. Those 13 are finally going to the lfs this weekend, I think they are awesome but 2 in enough for me.

What?
So as per the TBS site they are black urchins so I'll go with that lol. Even though they are purple-ish also.
