Having anonymously skirted around the Nanfa forum for a few months I though it was high time I registered myself. I'm based in Bolton, England and my main interest is British native fish species (of which I'll mention more at another time) but I do keep a small number of US species such as rainbow dace, pygmy sunfish, fathead minnows, rainbow shiner and diamond spotted sunfish. North American species of fish are very difficult and expensive to obtain the the United Kingdom and a few species such as redbelly dace and pumpkinseed are actually illegal to keep without a license. Great pity on both counts as you are so lucky to have such a fabulously rich diversity of native species in the USA. In the UK there are only a few dozen natives and many of them are really to big to consider keeping in aquaria so I restrict myself to the smaller-growing species.
I've learnt a great deal from the Nanfa forum about keeping of the few US species that I do have so thanks to everybody who has contributed. Sadly, there is no equivalent of Nanfa in the UK. Maybe I should start one...
Do you have any experience with keeping your local sticklebacks? We have some fresh water varieties here on Long Island, NY. I have tried some in captivity, but they seem to lose weight and eventually perish. They eat (brine shrimp), but
don't thrive. Their behavior is pretty interesting, and I'd like to keep them long term.
