I literally find mushrooms, in random places Constantly.
Example 1.
what the heck you doin Earl?
Discos be Poppin up in rock that was seeded with recently dead coral skeleton. I've got 3 entire rocks I refused to use again because they are covered with multiple clusters of "so-so" shrooms. I'll frag off the ones I like, and give the rocks with the rest of the life on it, to my LFS when they reopen. Everyone says mushrooms are super hardy. I find it to be a very mixed bag. I've lost 30 to 50 mushrooms since the fire. As far as percentage goes, proportionally I think I lost as many of those as I did to euphyllia. Less than SPS.
