Great, thanks. I do have them both in the lower part of the tank, because I got lucky and not because I knew what I was doing. They are also in low flow areas as that is the same advice the LFS had on placement.
One was attached to a tiny shell and the other was attached to small gravel/crushed coral. Will they turn loose of those things and grab hold where I put them, or do I need to help them somehow?
Thanks,
