heh i am not sifu yet.Still a learner.currently have no special strain guppy on hand.I have only 5 guppies.Plan to get more once i attend the guppy fan club gathering on 23rd october.

(This falls in the inbreeding section)
F1 means the first generation born from the original parents(where the parents have no relation at all).
F2 means second generation involves between the son and daughter(close relation).
F3 means thirdd generation involves between the son's son with daughter(close relation)
and so on.

Outcross means there is no relation between the guppies.Hm.. where u from? just wonder how u get those female albinos.I been lookin around in kl and found none.U can actually mix them but make sure dont overdo or else it will produce weak offspring also.

u may still get some healthy fish which able to grow full size.But as u further on(F4 below),the number of weak fish would increase.Most of the weak fish wont be able to grow full size and some might not even grow and stay at the fry stage after 1 month.
