Aquarium Advice Addict
Beat advice I could give is to make real sure it doesn't have aptasia on it. It's not rare to find it with those pests attached. It doesn't really matter if you get a little or a lot. It'll grow as long as you have a light over it. Cutting it is simple. Just use normal scissors on it in a small container outside of the tank. You don't want little pieces getting thrown around. It's easier to catch any tiny pieces when it's in a separate container than if it's in the tank or filter.
