My tank is more than 8 or 9 years old. It is pretty rock solid as far as
stability goes. I have a good skimmer and a good reactor going I
barely touch it other than feeding. I don't think "stress" is a viable
answer. To me it seems more likely to be happy normal reproduction.
The anenome is always fully inflated and visually it looks pretty happy
where it is. The tenticles are sometimes straight and sometimes extra
inflated with a ball shape at the ends.
The reason for my post was I was so surprised that it split twice in
such a short span of time. I have had it in my tank for close to a year
so far and all of a sudden wham!
