Did the same thing when I was kid. Even moved it up closer to the flourecent lights (20yrs ago so yeah you can laugh) and fed it. Thought I was doing good keeping an anemone alive. Then it had "kids" and I thought that was really cool! Thank god my brother shot the tank with his bb gun and I learned what they really were as I mowed lawns saving up for my new 20gal high. (another fun kid fact-you can acclimate Wal-mart figure 8 puffers to saltwater, they don't get very big, but they make damsels seem like angels)
