Hi there angus,

From the pic you have provided, I would guess that the animal on thr left is a male, and the one on the right is a female, however, this is only an inference, and may not be the case. If you can post a few more pics, preferably of the heads and tailbases, perhaps we could give you a better guess of the sexes.

I will respond to the rest of your email later on this afternoon, as I am off to lab right now. Cheers,

bob

bob..thx for your reply in advance..but from the above pics..maybe it cant show the right scale and cant c claearly..i would try my best to take more pics in the two days and send u..cos i know its a kind of shy species..i seldom handle it and hvnt take too much pics of them..~

normally..male should be little bit bigger in size with a bigger head...right~???

cheers.

Hey angus,

I just sent you another email with some more info from my own experiences with them. Yes, males will typically be of a larger build, and have a larger, broader head. Females are usually pettite and have smaller, narrower heads. Hoever, like I said before, this may be misleading, as I have been fooled many a times before. Tailbase is another somewhat definitive way of determining the sex as well, although not perfect. When looked at in cross-section, males will have a more triangular shaped tailbase, and females will have a more round, circular shaped tailbase. As the animals mature, and put on good body weight, this becomes more clear, than when you might first get them in and they are very dehydrated and skinny.

In my experience, females do not feed as voraciously as males do; in fact, I usually separate the pair upon getting them, in an effort to get the female feeding strongly off of tongs/hemostats. By making sure she feeds directly from me, I can then introduce the pair together, without too much worries. Usually, the male will eat the female's food too, if left in the cage for her to eat at her own disgression(usually when you have left her sight). By getting her to eat from your hands/tongs/etc, i think that will be beneficial to her success..

So maybe, the more voracious feeder is the male, and the less-voracious eater is the female. For this is what I have seen in my collection, with exception to my V. macraei.

I hope this helps a bit more angus, I'll talk to you later... Take care, have a wonderful day..

The ODatriad

the one on the left, is male, the one on right is female. Good Luck they look like beautiful healthy individuals. FR

i hv already keep them for several months..both looks quite healty..just one eat more but the other one not eat very much..so its easy to c one were fatter than the other one..they never show aggressive toward each other...and they would sleep close together at night..so i always imagine they should be a couple..but now i begin to worry about am i right or not.
