paul_r Posted April 3, 2008 Report Share Posted April 3, 2008 Hey guys after tons of feeding and water changes my fancy guppies are finally breeding, as usual tank if full of fry, that is fine i shouldnt be complaining but approx 95% of fry are female, temp is on the low side, around 22 degrees celcius. Would this be the logical reason there are mainly females? My breeding males are very beautiful and it is irritating to only get females any help appreciated Paul Quote Link to comment Share on other sites More sharing options...

Caryl Posted April 3, 2008 Report Share Posted April 3, 2008 There does seem to be a connection between temp and sex ratio. Quote Link to comment Share on other sites More sharing options...

Keri Anne Posted April 4, 2008 Report Share Posted April 4, 2008 Temp does seem to effect gender try around 24-25 degrees. Quote Link to comment Share on other sites More sharing options...

Caryl Posted April 4, 2008 Report Share Posted April 4, 2008 This is a family forum you know :lol: I was going to suggest you spent less time with the guppies and more with your wife but... :lol: Quote Link to comment Share on other sites More sharing options...
Simian Posted April 5, 2008 Report Share Posted April 5, 2008 I assume the same would apply to other live bearers. I isolate (to another tank)my females when looking on the bigger side I wonder at what of the pregnancy sex is determined? Fish can be funny re changing sex...anyone know/hazard a guess?

Keri Anne Posted April 6, 2008 Report Share Posted April 6, 2008 Don't know.... I've only proved it with guppies. Quote Link to comment Share on other sites More sharing options...
sherwin Posted April 18, 2008 Report Share Posted April 18, 2008 My guppy dropped 79 then 20, and I only see about 5 females (all 1 month old). My temp is roundd 24-25c and ph is round 7.6. I heard that high ph gives you more males. Not scientific data though Quote Link to comment Share on other sites More sharing options...
