Re: extra male Aggie Alenquers

[Ken Roese <ken1@iwaynet.net>]

	I did notice a little difference in the blues. Thought it might be
something to do with the photograph more than the fish. I've also heard
stories of collectors naming fish for a collection site where they were
never collected from to protect their fishing holes from competitors, thus
I just wanted to make sure.
	Now, how can I get a larger female ratio? Lower temp or Higher temp? I
have read temps can decide the sexes in apistos and pH in west africans. My
WA's I can get a good ratio, my apistos are always skewed,

Thanks,
Ken
