white puffs in between zooanthid polyps

[Myka]

The Pineapple sponges aren't rare, and not difficult to grow. As your tank matures you will find them popping up all over the place, but mostly in the sump, filter chambers, overflow, etc. I'm not sure what kind of Zoas those are since they are closed up, but I know my Zoas are all nice enough that I wouldn't think twice about pulling Pineapple sponges off them! I would also try to separate the Frogspawn when it is large enough as the Zoas and Froggy will sting eachother.
