What are these?
I was wondering if anyone could tell me what these three things are.
The first pic is some kind of worm that seems to turn itself inside out to grow larger and reach for food off the rocks, I have a few of these in the tank. The next two pics are of something I just got today on a new piece of rock, then I noticed another one under an older piece of rock. it sort of looks like a pigs foot or something, very small only about a 1/4 or 1/2 inch across. It's next to the hermit, sort of a greenish-pale color. The next pic is some kind of sponge I think.
My tank is a mini reef (6 gallon eclipse)
thanks in advance,
