Hello, I am brand new to the hobby and the forum. I just started a 75g tank about 5 weeks ago and I think it is about cycled. I just have live rock and a couple of damsel fish to cycle the tank right now, but I have a little critter on a rock that I can't ID.
Anyone know what this little guy is? It's about the size of a dime right now.
