choosing genders???

it is true that you cn choose the genders of your fish by temp. but do you think it is right?

I've heard it works with guppies, but I can't remember which temp is supposed to yield which gender and I don't know if it works with all fish.

I know that with my african cichlid fry I tend to get more females than male and the tank temp generally stays around 80*, but I haven't tried lowering the temp to see if I get more males.

Ive too heard it, and I really dont have a problem with it, ive heard that the amount of seamen a mammal produces can determin the gender of the babies.

I didn't know temp would affect the gender of a fish. This is kewl, so what do you have to do to get more males?

I've heard that temps can influence the sex of guppies but i don't remember which temp influences which sex. I don't really see the problem with it as it isn't artificial.

I want more males. They are so beautful. I have one female fry that has a blask tail thought she is also beautful. But I seem to have 2 males for 44 fry so far although the last 7 are only 1 and 1/2 weeks old so I am not sure. I would love to have a few more males. But I keep my tank about 80.

This sounds like a cool experment (nothing that will hurt the fry though of course). I will let you know if I get any different results from my new fry.

Also doesn't the water temp determine the length of pregancy also. My mom had her first 2 batches 30 days apart but the last one was only 26 days. not that I expect her to be right on target but I thought 30-90 was the adverage. I guess they are like humans. I kids wanted out early to all 3 of them were born early. My first son was 1 month early my 2nd (only daughter) was 12 weeks early and my last was 6 weeks early. Maybe fish are the same way?????
