Congrats on new ray. Glad to see you dove in with a high dollar ray but a little shocked you went to the top of the ray mountain but need advise. Best advice I can give is clean water, lots of room, do not over feed, and leave them and the tank alone. You and your ray will be much happier if you add the fish you want to keep then leave the tank alone. We have all got into lots of trouble cycling fish and rays in and out of our systems. Stability is key
