How big do individual polyps get on green button polyps (zoanthus
polchellus)? I got it 2 weeks ago and the largest polyp was about
1/4 inch across. Most are now about 1/2 inch across. At this pace
they will grow out of my tank and take over my living room before
too long ; ). I know there has to be a maximum size.



I have 3 different color variations, all are approxamately 1/2" in
diameter, and show no signs of getting larger. Your polyps were most
likely just not opening fully yet. Once they adjusted to your tank,
they opened to their full size. However, read on:

A aquarist friend of mine spent some time in Germany recently. He
discovered a difference between most German fishkeepers and Most USA
fishkeepers. In the US, button polyps are often kept in reef tanks,
and many strive to collect every color variation they can lay their
hands on.
In Germany, the "pest anemones' as they were commonly referred to
as, were shunned, being classified along with aiptasia. The reason
for this is their tendancy to spread. You take a small bit of LR with
2 polyps on it, place in on a nice spot in your tank, and they will
multiply. I bought a orange\green colony that consisted od 8-10
polyps a month ago, that colony is now about 70 strong. They're tough
to kill too, I have had a couple colonies pop up in new location
where I didn't want them, and I had a hell of a time removing them.
