at the mo I've 3 at home, 8 at the girlfriends and 6 in the fish hut.
Hate to say this but Davy (the boss,will be offended. This predominately a UK website(he's from Alloa I'm Glasgow, Tatya's Perth, Mac' is from inverness etc.) we do have a few foriegn members coming from New zealand, Finland, Canada, south africa and a few other places. so we're an international comunitty. if you want to find out where someones from they should have it posted bellow there name.
Most of the local breeders are usuing standard shop fish to start with. the ones that have anything decent don't seem to want to part with them for less than an arm and a leg.
I've a mate thats breeding some crown tails at the mo but they won't be ready for a while. he's trying to get them as pure as he can first. It may be an idea to ask your lfs if they can get any fish you want in. either that it's try the online auctions. I'll have a hunt about and see who's got what for sale in the meantime though.
Have a look at the main site. The links at the very top of the page. www.tropical aquariums. co.uk
oooops. sorry didn't read your post right. Yes most of the stuff on the web is American. All the betta breders in the UK I know. don't have websites. So it aint easy to find them. It might be an idea to join a local aquarist society.that way you find out who's doing what in your area. there are also auctions and meets happeing every so often. There's a thread about some dates in general or tropical chat somewhere. Where are you from. I may be able to point you in the right direction.
