| I don't have zanthos in my tank, but I do have other items. I believe that if you get strong bulbs that fit in the tank hood you can have them. However, I don't keep them because they are poisonous. I do have sponges, xinia, mushroom coral and green star pollups. If you are still in question, ask your local pet store where you bought the tank, or go to oceanic.com and ask the manufacturer. |
