looks like a ton of algae to me. The brown thing growing also looks like some sort of algae. does it have the consistency of a leaf to your touch?

i havent touched it but its not growing on the rock. its growing straight out like it's its own little thing. and i blew on it with a syringe(sp?) and it didnt break, so??
