As I understand things with shipping, you might be better off to acquire stock from the west rather than the US. If you were to let us know what species you were looking for, Lisa might be able to at least point you in the right direction. I brought some fish to southern Ontario last year. The hobbyists that are now working with these colonies might be producing fry (I don't know for sure). I know there were Neochromis rufocaudalis, a couple locales of Pundamilia nyererei as well as Pundamilia pundamilia, a couple Xystichromis species and Platytainiodus too. I can't remember everything but there were some great starter colonies and some enthusiastic fish keepers. I would expect good things from them.
Here is what I currently have for Vics. I'm trying to expand my array of breeds so if there is anyone that sells them in Canada I would for sure be more willing to deal with them and buy breeding colonies from them. I'm interested in buying from the US too but it just seems ALOT of companies will not ship to Canada let alone New Brunswick
It's not so much that they won't ship, but many of the carriers refuse to bring in live fish. Also, customs is getting tougher and tougher on aquarium fish. There are a LOT of new regulations going into place now.
