I've had this mushroom for one week as of tonight and I thought I would give an update. So far, so good. The mushroom opens up everyday and displays nice color. I've got it mounted low in the tank, on a slanted rock face so it doesn't get full, direct light. It may like a bit more light, but I'll be adding reflectors to my T5s next month and I don't want to shock it. Here's a pic I took yesterday.
