My name is Amy. My daughter got a little RES last May and I really didn't think it would live. I have read all I know to read to make sure we are doing things correctly and we must be because this little bugger has grown so much in the past 8 months! He went from a little bowl to a much bigger bowl then 5 gal tank and now to a 20 gal tank. I believe it is too small but we are planning to put him outside in his own little pond come May. He is pretty cool.
