Itty Bitty Diadema urchins?

[AndyL]

Picked one up at elite - 21.99 Got home expecting a ridiculous acclimatization period (urchins... sg changes...) amazing - colby keeps the tanks at 1.025! Should be a quicky...

Was looking at the one with the thick spines - interesting lil guy... But I wanted diadema - hair algae control + lack of decorating with zoos and other corals

(there's one left - dimeish body size, 1-1.5" tip to tip)
