Ah. In that case I would import eggs, What a golden opportunity to spread a rare (even though common elsewhere) colourful fish,Hmm, knowing this, makes it even more frustrating! What you should know though, is that I am living in the south of the country, in the second poorest state...... Not many people can afford to have pets. What is sold most here, are goldfish (you don't need a heater, people don't use filters etc.) and livebearers, which are cheap. And the shopkeepers know very little about fish too, so can't offer anything special.
I wish I lived much closer and I could get eggs to you more easily,
How is you postal system is it quick or can it take quite some time to recieve mail.
On the egg front I think you would be better going for
Africian or South American Annuals as their eggs can be incubated/rested in peat (diapause) for different lengths of time and would be more suited to arriving safetly.
Anyway see what your dealer turns up first and let me know how you get on
