I just purchased a Ricordea this weekend and want to make sure I put it in the correct spot in my tank. I have a 70 gal and we are running 330 VHO lights. Right now they are about the middle of the tank. I actually got two of them on one rock. The one seems to be curling under and the other one seems fine. They are the same type, just different color. Checked the water, everything is fine. Any suggestions would help. These are my first and I don't want them to die.
