I have a question regarding one of my reef tank inhabitants. I have a green star polyp (Pachyclavularia sp?
thanks to help from the crew, now totally covers a 6″x10″ rock with a beautiful mat of bright green polyps. It has advanced in one direction partially covering another small rock (which will be removed eventually to a friends tank and another rock put in it’s place to repeat the process…doing my small part to keep more coral in the wild). The problem is the other side. The colony has somehow spanned a 3/4″ gap between rocks (I thought would stop it’s advancement) and has climbed another rock and is advancing towards my Anthelia Polyp colony. The space between the two colonies is now only 1/4″. Moving the rock is not an option and I really want to keep both colonies happy because they are both doing great and are very beautiful.
