I was happy to get my first ricordea yuma, which happened to be off an ebay auction for around 30 bucks. Taking it out of the bag I was surprised to see that it was not attached to any kind of rock or substrate. I also noticed the center looked funny, no mouth, just little white squiggley shapes. I used the net method of attaching the mushroom to a rock and since have seen some of the little squiggleys fall off into the tank. The yuma hasn't shrunk or shriveled, and the orange body is still very vibrant. Any ideas?
