Water Affecting Sex Of Babies.

[mrs_darlington]

I had 9 Endler babies all turned out to be girls, what I have been wondering is would something in the tank affect the boy/girl ratio??

i don't know about endlers, but with kribs, if the ph is below 7, you tend to have more females; if the ph is above 7, you tend to have more males.

How old are these fry? Most livebearer fry are born female, and any males will only appear so once they are mature enough.

From my understanding, livebearers are born either male or female, just some males develop the male characteristics late.

Thats what i meant, sorta. When the fry are tiny they all look female, but as they mature the males become more apparent amoungst them.

As far as i am concerned, normally the water temperature will affect the sex of fry, not the PH, esp for endler , guppy, platy etc.

The fry are now 6 weeks I think, the platys I got from dingweding were all girls too which is also why I wondered what influenced sexing?

The males and females (Endlers) are quite different so would be easy to sex - or so I thought.

Well i keep my water at 80F and i almost always get boys, maybe 1 in every 20 is a female

I really wanted some boys they are so pretty!

They might not be mature enough yet for the males to become apparent amoungst them. I've read about the water temp/chemistry thing, however as far as i am aware it doesn't work on livebearers and that the frys genders are decided by the genes and hormone levels of the mother fish. Livebearers grow their young inside them in the same way as we do (except of course the fish are much more primitave) and the same rules apply to them as for as i am aware, at least to a large extent.
