I bought this in April. It opened like this until late September and then shrunk and no polyp extension.
I was thinking about removing it, as I was starting to become concerned it would start breaking down in the tank.
No param changes in the tank.
A week ago it started opening up again, although not yet to this size. Polyps are extending again.
Anyone have experience with these? Do they sometimes go dormant like some leathers?
Thanks.
