I have a FOWLR and the last few days I've noticed somthing unusual on a piece of LR. It looks like black fuz with white spots around the outer edge. It was about 1/8 in in diameter when i first saw it. Now it's grown to about 1/4in. When it's open it looks like fuz. It has changed shape lastnight and is longer. Anyone know what this is? Should I leave it there? It's definety living seems to close alittle when touched.
After a little research could this be some kind of chiton?
