I had a piece of sponge growing on a small zoa I have. I pulled the sponge and a few of the zoa heads came off with it. Can I clip the small individual heads off and glue them to a rock and expect them to grow?
Yes. Just be careful. Zoas contain a toxin that can make you sick if it gets in your blood stream. Wear safety glasses and wash you hands really well after you handle them
On the mat?? You mean what they grow on, the stick-like thing? This is a very small bunch, maybe six of seven heads and I don't see anything like that, they are sticking to the sponge or to eachother.
