urchins and wrasses
 

Hi all,
any of you guys have experience with wrasses like a sixline being compatiable with urchins? ie: longspined??
thanks your imput is much appreciated! :biggrin:

They will totally ignore each other, that is, if an urchin can be more antisocial than normal.

I have 3 urchins in my tank, a black long spined, pencil and another spiney(2'' long reddish spines) along with a 6 line, yellow and a cleaner wrasse, not to mention a lot of other live stock, but these fish you questioned about in my limited experience don't bother each other. The only problem I have with the long spined urchin is it seems to enjoy munching on green star polyps and all the urchins like to wedge themselves into spots that are tight and push some coral and rocks over or off a ledge. But all in all they are quite cool and the wrasses are awesome.
Good luck.

do any of them eat coralline algae?

Urchins will. They mow through that stuff.
