Sorry - I have seen Mary-betta-fish's postings, I never thought to contact her directly! But thanks for the advice - I never knew there would be a fish-fanciers group, but I bet there is - we have a lot of fish specialty shops in our area, so there must be a big interest. I am about to enter a new world I know nothing about, and I will really be the one getting the fish, not my 4-yr-old!!!
