Ive had this ricordea yuma for about 3 weeks now. it has grown slightly but lately I find it upside down. No matter where i put it in the tank the frag is always face down I havent figured out if the royal gramma keeps knocking over or if its the emerald crab/snails. I have not glued the frag i have no experience gluing anything in my aquarium. what do you guys recommend I do?
