Possibility of determining gender on younger axies?

[kenya]

I know it's not really possible to figure out the genders on 4-5 month old axolotls, but, what about close guesses? I think my leucistic is slightly older, it's quite a bit larger, and always has been. But it's also always been very rounded. The wild type has always been more lean. They are both starting to get those nice little bumps under their tails, with the leucistics being much larger.
I know I can't really know until they are older, but, will they really change that drastically? I figure the leucistics bump is bigger because it's older. [I would guess so, I never asked if they were from the same batch, but even it's head is larger.] But even with the wild type eating better than when it first got here it's body is just not rounded. Just curious I suppose. I will try for pictures later, any suggestions on what angles and such would be best?

It is very tough if not impossible. At that age I have had "females" that were actually males and vice versa.

I have two juvie axies that were born in early November last year. I thought I had it sussed, 1 male, 1 female, but the 'female' has now decided it's a male! Well, not really of course, but the other juvie (his brother) was always the biggest larvae and developed his 'maleness' earlier (like a month or more earlier) I just assumed that the other sibling was a female as he/she wasn't so well developed in that area!
I put the second juvie in the tank with his brother and Dad yesterday and straight away the two juvies were showing off to each other, cloacas open. (If they were more mature they would've been dropping spermatophores!)
Anyway, the moral of this long, convoluted story, is that you can never be sure, until you're sure, if you get what I mean!

Huh, well that's interesting. I guess I will just wait and see how they grow and develop then! I hope that the white one [Lola Ray, decided against Gwen Stacy] ends up being female. I hope that whatever genders they end up being it's the same gender so I don't have to worry about eggs!

When my late axies bred, i could determine which were male when the axie was only a couple inches in length. I separated the 2 i thought were male and the 2 that didnt have lumps that i thought were female and after a year, they turned out to be the sex i thought they were.

They all had the toe tips (black on the 2 leucistics and white on the 2 wildtype) at this small age. I think i was pretty lucky with my guesses but if the cloaca isnt enlarged then it can go either way really until the axie gets to around 12-18months when this can definately be determined.

I think its pretty much pot luck when buying juvenile axies!

Interesting. My sister correctly sexed five out of five of my Axolotls before they matured (at about 4"ish); although I couldn't tell (and I'm more 'into' Axolotls than she is).

She said their bodies were slightly differently shaped (along their back if I remember correctly), of course it could have been just a lucky guess. I'll test her again later in the year

Note: this was her own observations; and nothing scientific.

If its of any consolation, my leucistic "Zeus" just deposited eggs on the anubias. Now i have to rename her "Persophine".
