I'd love to have them reproduce quicker, but at a total of 60w of light that's unlikely.. unless yo have some tips?[/quote]
YEah, that's the ticket. Mine didn't really reproduce till I got a larger light. They will move to satisfy there own light needs.
If you did want to move the larger ones, then just cut them with a razer blade or sharp scissors about 2mm from the base. Wrap the top in mesh and an elastic band to another piece of rock and they will reattach in a week or so. You will also get a new mushroom from the base that you cut off.
they thrive based on light. I don't think that any supplements help them, but they are very sturdy corals. I had so many that when I changed tanks I left a handful just sitting in the old tank with no light or heat. To my surprise they were still alive weeks later.
