I just purchased some large Green Fluorescent Mushrooms from liveaquaria.com. They specify 5" - 7" in size. I was expecting a number of fairly large mushrooms, but what I received is a rock with quite a few very small mushrooms. The largest is barely 1cm in diameter. I am not exactly disappointed, but I would like for them to get larger, not just more numerous. Does anyone here know how large these critters can get? They are very crowded on the rock I received, so I think they have fully blossomed at their current size.
