How to tell if mushroom is dividing

[Roachant]

Hi all, I recently got a green mushroom for my 80l nano and I noticed that it was spread out quite large one day and then the next half of the disc was folded with a dark band running along the disc where it was folded. When I looked at the stalk it looked like there was a split but I couldn't see well.

Is my mushroom not well or is it dividing?

It may be splitting. I have one now splitting.

 

Mushrooms are hardy. They will shrivel upand get a mushy look when not doing well

Thanks for the reply! I don't think he (it) was splitting, it has returned to a spread out state .

I did a 20% change to be safe and I moved it to the sand bed because the light might have been too strong.
