They are trying to make a sale or they dont know what they talking about. Stick to LPS, or mushies, or Zoas. Look into mods for the tank. They are SO worth while. NO ANEMONES unless they are non photosynthetic. NO SPS. RESEARCH!!!! Then you can have fun, be successful, and learn to know what you are doing. Good luck. BE PATIENT, and ALWAYS RESEARCH FIRST>
