My lfs gave me a deal on a large rock he had. He was rearranging a tank, and he knew I wanted mushrooms, so he gave me this 3lb live rock (about 7x3x4ish) with 5 mushrooms and 12-15 sponges for 20 bucks!! I was very carefull to keep it in water due to the sponges, and slowly scrubbed what algae that was on it off. I acclimated it for a little over one hour, and put it in the tank. He mentioned that the mushrooms would "prune up" when they were aggrevated, and sure enough, they did. My question is when should they "unprune"? I have 3 new "baby" mushrooms on pieces of rock that were already in my tank, so they are spreading, but are the big ones ok? How will I know if they have bit the dust? Is there anything I can do to help de-stress them? Thanks!
