I have just recently starting a 45 gallon salt water tank with live rocks, live sand and some starter fish to get the tank conditions. I am hoping in the next few weeks to start adding coral. What is the best coral to start with? I don't want anything too difficult as this is my first salt water tank. All my test are good and the water is ready for me to add more fish plus coral. I want to give it time before adding coral as for now it's just the fish and bottom feeders.
