Has anyone ever heard of hard corals growing in a zero light, high ammonia environment? I'm currently curing some Lalo LR in a cooler with a heater and powerhead in my garage. When it came in the box from Live Aquaria it had a lot of small hard corals growing on it along with some macro algae and soft corals. I expected most of it to die off during curing and then grow a little when I put it in my main tank. So far the corals have been growing(though very slowly) and aren't discoloring at all. They keep scratching my skin when I scrub the rock during 100% water changes. Any comments?
