| Tank set-up question I finally got my tank as an early Christmas present, it's a 75-gallon with a wet-dry filter and a canister on the back. My fish store said I could just fill it with saltwater and put a couple damsels in to get it ready. They told me to get crushed coral but I keep reading about people using sand. What's the difference?
Do I need live rock? What kind of damsels should I get? They had lots of different ones.
I want to start with a couple fish and then get corals as soon as the water is ready.
Thanks!
