Thank you Viper for the link. The first pic is more like what I have. I messed with it and it since retracted into the rock and hasn't shown its' self yet. I'll get it tommorow with the boiling water and turkey baster....Should I take the rock out of the tank and do it or should I do it inside? The rock is about the size of my fist and it has about 4-5 mushrooms on it. Anyways what is the best way to blast it.
