Thanks.

You've really been a great help. Since my intention is not to breed a particular strain of guppy, I'll just set up my tank with mixed guppies and let them inter-breed happily. It will also cost me less to acquire the guppies since I won't be looking for a single variety of guppy but will just get whatever is pretty!!

Ooooh, now I'm getting fired up thinking about setting up the guppy tank next week.

Thanks again.
