Bounce Discosoma?

[eastgill]

Anybody know how common a Discosoma bounce mushroom is? I have one that’s been developing the “bounce” for a while now. (Ignore the dirty water and spaghetti worms, I just fed) When I had originally bought it, it didn’t have it, or at least it wasn’t big enough to be noticeable. I only ask because it seems like most of the time when I see a bounce mushroom it’s a rhodactis

It's not common, but has started becoming more common in recent years. It seems to happen with LED lighting.
