I purchased a few frags from the LFS about 3 months ago and placed them in a small tank to observe.
During that time, I noticed a piece of live rock I placed in the tank and which I've had for years develop one head of Aptasia. So I pulled the rock and placed it in a small display where I could enjoy it and keep it under control.
Today, I took a look (with my glasses on) and noticed there were now three Aptasia heads. And I am also noticing one head of Aptasia on the back wall of the tank and on the overflow.
I can understand the rock developing more and more heads. But how it is growing on other areas of the tank? Do they release spores that travel around the tank?
