Hey everyone. I'll be moving all of my corals from a 12 ga to a 28 soon but I only have one issue. I have some corals in my 12 ga that are growing on the glass on the sides and back of the tank. Does anyone have any good suggestions on how to properly remove them so I can place them in my 28 ga when I get it and don't harm them? I was thinking of maybe a razor blade but I wasn't sure. Thank you all for your time!
