Uhhhhh wait, lol you said tuxedo urchins.
I'll guess I'll have to research a small urchin and see if Petco can order it for me.
Or maybe I'll try and get one in S.A. soon.

Oh and another thing, I need to replace my lights.
It might have a lot to do with my growth of green hair algae.
What sucks is that I have no place to get it locally so I'd have to order it.
