Hello All,
My tank is in the process of cycling and I spotted this strange-like pink plate. Stranger still, it is pretty mobile. At different intervals in the day I have found it in different places on the rock. I have searched around the net for hours on end and can't seem to find an answer... Help please? Thanks!

Beginning of Coralline algae... nothing to worry about.

hmm.. well now it has moved all the way to the edge of the rock. Sometimes it looks like it is completely standing up too. Weird. Looks like it has a rubberish texture. I dunno...

maybe a mushroom?
