Hello everyone, i haven't been around in awhile but my tank is doing great. have not had any fish loss and everything is doing fine. I do have something strange growing on one of my rocks. they are green and shiney and look like bubbles (i think they look like glass balls). They are only growing on one rock. Does anyone know what they are or if they are dangerous to the tank. I tried to remove one and they are hard.
Any ideas?? should i just let them be?
