mind my asking, what is particularly expensive right now about the guppies. Is it really a matter of money or is it of time or the effort of learning about the proper care of guppies? I'm not disagreeing with you about expense in all three of those areas, but sometimes there are some workarounds.
I think that it is important, especially for women, to keep a certain amount of anonymity on the Net. But, in a general sense, where do you live? For instance I live in the southern 'burgs of Chicagoland. Might you live in greater Pittsburgh or the NY city area type of thing?
And while I would try and persuade you to stay with your guppies, if you don't what will you do with them? Please say that you will not flush them.
