Thanks for your suggestion. I will use the real coral. I very new to this. My tank will be arriving in about 4 weeks. So I have long while before I can introduce the seahorse. This is my first tank. Which corals are the best corals to use.I hoping I can have a lot of color. Whats the best live rock to get? I am going to get black live sand I just have to find it. Should I get them from the internet or a store? I guess I will need to learn auquascaping also. Do you think I should use a u-shape formation? Can I order live rock in advance, or did they need to be in water at all times. I want to make sure I have the best for my buddies to come. Oh the mushrooms which are the best and most corloful.
