Two Spiny Black Sea Urchins

[rail]

Getting a bit large for my tank - approaching 6" overall diameter. Will take $20 for the pair - just want to find them a good home. Will have to be picked up in the Flint area.

Could I take just one of the urchins for 10? How big of a tank are they comming out of?
