So far it is staying. No reason to kill it yet.
VT, Cool to know that it sounds like whatever it is I can move it.
RFB, Hard to find info on the ball anenome, although there are lots of tourist pictures of them. I will do more research tonight. (Kids are on spring break)
Z, I do thank you for your kind offer. However considering the current bio load that you have in your zoo, I mean house, I would not feel right with burdening you with another living thing.
It does look pretty cool though. It has an orange middle and green outside like the zoos around it. I hope that is not from eating the zoos, you are what you eat.
