I agree that those reefers who can, have an obligation to frag, propogate, and trade, sell, give away, whatever, as much coral as you can. As long as you are able to propogate healthy specimens, and without spreading reef vermin, spread the frag wealth and keep the hobby out of the ocean to the GREATEST extent possible.
I have been using just a small rack in my fuge, but I am getting more and more cramped for space.
I recently had to expand the rack to hold these two clams that were getting nipped (until I can catch the nipper) ... but this expanded rack is already full.
So I am moving this 90 g (bottom of the pile) in to a space on the wall behind my fish room for a dedicated frag tank FIANLLY!
