I have what looks like some sort of anemone growing from a LR
It is a brownish green color with a large "head" with small tentacles around the outside. There are also tentacles on the head closer to the mouth in what appears to be a random pattern. The mouth is a small white/tan slit. If i put my hand or a tool in the tank to clean the algae it will retract down into a hole in the LR
. I've looked through different links in this forum but have yet to find anything that looks like it. Sorry I have no photo.
