I have a hugh green frogspawn the size of a vollyball. some of the branches facing the light are doing well. The branches facing down only open half way. I want to break them off to place them facing the light. The branches are 1/2 inches in diameter. Can I just break them off with my bare hands? A few months ago, I saw someone cut coral branches using something that looks like a big toe nail cutter. Do you know where I can buy one?
