very beautiful looking zoas and i love the purple color of the last

i am a reef beginner and will like to know how you can grow your zoanthids into ball-shaped colonies.

I know zoas can't grow on sand, but will it be possible to control/manage their growth on live rocks?

If you have you're zoas on a frag disc sitting on the sand they will naturally grow into a ball as they have nowhere else to go.

If you mount them onto your live rock they will continue to spread along the rock , however that makes it much more difficult if you ever want to frag them , unless of course the rock they are on can be easily removed from the tank.

Awesome service!!!
 

Thanks so much for the extra efforts on getting the frags to us! They look beautiful and I can't wait to get them into my tank. Thanks again, man.:biggrin:

You're very welcome , it was nice meeting you.
