I just got my first SPS acros in my 10 month old tank. I understand placing them at the top with sufficient par and flow but typically how much space should you leave between each frag? Can they entertwine each other as they grow with no issues? I currently have about 5" of space between the frags. I'm assuming also if I buy 2 frags of the same genus like Bali slimer I can place them fairly close together?
