Guys, wanted to share an interesting and puzzling development. I got this small rock with a few zoas from one of the reefers a long time ago, must have been at least 9-12 months ago. About 30 days ago I noticed something small growing, thought it was a few closed up zoa polyps clustered together. It is now clear that its some sort of a torch. Doesn't look like its from any of mine, so must have either hitchhiked on this rock or one of the plugs. Does anyone know what type of a torch this is?
