If they are true albino, you'd breed one to a regular heckelii and then breed one of those fry back to the albino parent.
Correct, statistically a cross between a carrier of the albino gene and an albino should produce 50% albino offspring, but this may only express this way when large numbers of offspring are compared. IOW it can be like tossing a coin in smaller spawns. Either way I would think that it shouldn't be too long before albino heckelli are being produced on US soil.
