Sexing axolotls

[Donna001]

I recently had to split my older axolotls into 3 separate tanks as they were maturing. I know that males have a larger bulge than females, but I just wanted to post some pictures and get some opinions before I decide which ones can go back into a tank together.
I have attached 2 pictures of one of my leucistics, which I think is male.
I have attached 2 pictures of my wild type, who looks different every time I look.
I also have another leucistic, but I'm struggling to get a picture of that one. Will post when I can.
All are less than a year old, so I really don't want any unexpected breeding happening.
Appreciate your help & opinions.
Cheers.

I got some pictures of my other leucistic.
I figured that this one was male because if I could see a bulge from above, at the top of the tan, then it must be quite prominent. I also got a picture through the hide.

Both of the leucistics look male to me and the wild looks male but I'd hold off on that cause it is a little less full looking in the second pictures. Tricky little wild one.

Hi Sully,

Many thanks for your help. I thought that they were all males, but they are all still in separate tanks at the moment. Your pictures are very useful, I didn't quite realise how small the female cloacal region would be, even though I looked at the pictures on this link:- Axolotls - Biology
Your pictures make the difference more obvious.
I think the wild type is male as he was the only one with an obvious bulge when I got them last month. I thought he was the one who left me a collection of surprise packages all over the tank substrate a couple of weeks ago, which may be why his bulge isn't as obvious as normal now.
I'm going to keep them apart for a little longer as I'm considering the purchase of a bigger tank soon. Even though their first one was suitable for 3 adults, I've recently moved some tanks and have now found a place for a tank that would be more than large enough for at least 6 adults, just in case my other 3 juveniles all turn out to be males. :happy:

Again, thanks for your help. I was worried about mixing sexes as I don't really want to breed any of my axolotls.

Lucky you getting all males. Would have made life a lot easier had both of mine been males.

That's why they were put into separate tanks until they all matured. I still have another tank with another 3 juveniles, but I don't expect them to mature for another 6 months. As it gets closer to the time they will be separated as well, until I know what will be safe to do.
