Temp sex

At what stage of development does the temp affect the sex of an animal? Is it the same on most reptiles?

Can't be the same on most reptikles, becuase most reptiles have diff. egg periods. But in Leo's, its about on the 2 week mark.

That is when you would change them temps to 89 in the incubator to do the "Tremper Incubating Method". Wouldn't recommend it... many people have had very little hatch rate....other have not.

What I ment to say was, at week 2, there sex is set on eather male of female.

I have heard that it is the first 2 weeks but I have never tested that out.

why would you change the temp up to 89 after two weeks? to make your females hatch quicker, or does it have to do with color

Yea, it has to do with color. The colors are brighter, IMO it's practically "fake" color. It probably does reduce the incubation time by a tiny bit though..anyone else have any thoughts about that?

I heard it was 14 days 20 to be super safe (well read it on trepmers site)

Here is the info on the Tremper Color incubation temps but I decided not to try it since some people were having lowered hatch rates.

Katie, I am with you on this.... There are a couple of problems that can stem from this method..... Egg death, deformed hatchlings, "hot females", just to name a few..... It is almost falsely representing the animal also, if you do not let the buyer know it was incubated that way..... To me it is not worth the risk.... The color difference is not big by any stretch and how much quicker can you hatch eggs that way???? Maybe 5 to 10 days, if that.....

It is not worth the risk because the outcome in color is almost no different from eggs hatched out at stable temps.... And more importantly, it can pose health risks to the hatchlings if they even do hatch.....

is this how some super hypo tangs are made?

I'm sure some do it to other morphs but the practice in general doesn't seem common to me. Although you never know.....
