I am wondering what kind of corals would be good for the top of my rocks that would grow up. I have a 70g tank with T5 HO. I know I can't do acropora but I want that look. Any suggestions?
Why can't you do Acros? How many T5 bulbs and are they HO? There are many who keep sps tanks with only T5 lighting. Just remember, that lighting is only one aspect of successfully keeping SPS corals.
