Hi thanks for all the information. I wish the fish store had told me about cycling the tank and adding too many fish to a new tank. I killed 1 frog 1 guppy and 1 angel fish because the ammonia was too high. My kids were so upset. After reading your getting started section I realize that there are too many fish in my two week old tank. Well thinks for the information. I won't make such a deadly mistake again. Moe
