I have a group of 5 A. andersoni, and they turned out to be 1:4. In talking to two other keepers, they seem to have a surplus of females too. Is this just coincidence, or are there more females than males out there?
 
Initially it would seem that more females are produced than males. I think it's a little premature to draw any conclusions.
 
I would ask anyone who has andersoni to please post your sex ratio. If a dozen or so people respond, we will at least have some anecdotal evidence.
 
Yes, There are two pet shops here that is selling young adults, for 30 dollars each an they are all females!!! An the store owener got them for 15 !!!! It's the same as the boscaii, I've had 5 females for the last 4 years they layed every year an still have yet to get a male!!! I guess you have to be in a click!!!
 
I'm really surprised to have so few replies to this post. I'm sure there are people who obtained A. andersoni juveniles (unsexed) and now know their sexes.
 
The ones I just raised turned out about 50/50, of around 40 - 50 animals.
 
Of my five it appears I have one male and four females. Three of them are younger so it is hard to tell, but I would say they're ladies!

Could sex ratios be affected by temp,ph etc? having one person with a 50:50 ratio of males and females is not indicative of a general trend. Please note that this post was started with a question, i dont know the answer.
 
could it be a temperature -or environmental influence during development that warps sex ratios, like in crocodiles? Maybe in captivity they are raised at generally higher temps than in the wild?
 
Hi, thought I would add my 2 cents as I've been interested in finding more andersoni. I purchased one in 2009 and it is female.

    Had a question that I just want to be sure of. My marbled newt is a little over a year old and has started to develop and I noticed that he is starting to swell a little below his abdomen. I guess I’d like to know if they are his testes or if I need to be concerned.

    Hello!!! I'm new to this website and idk how to ask a proper question on the designated spot yet, so I'll ask here, I'm a first time Axolotl owner, and my dad used to run an aquarium store, anyways... Orca, my Axolotl, seems to loose parts of her toes on one limb from time to time, I can't seem to find the problem. Tempature is well, she doesn't seem to have any infections or anything, though. And I'm not sure if I'll be able to find a vet in Brazil for amphibians that are in a reasonable distance to drive without stressing Orca out too much

    Hello, I’m hoping for some advice please. Our Axolotl is about 7 months old. Till now no problem. Eating, growing and happy. He’s simply stopped eating. Everything looks fine, his gills look healthy and no apparent signs of sickness. He just swims past the pellets and bloodworm like he can’t smell it. I don’t think it’s a blockage either. Any ideas and suggestions for treatment would be much appreciated. Thank you!

    Dear All, I would appreciate some help identifying P. waltl disease and treatment. We received newts from Europe early November and a few maybe 3/70 had what it looked like lesions under the legs- at that time we thought maybe it was the stress of travel- now we think they probably had "red leg syndrome" (see picture). However a few weeks later other newts started to develop skin lesions (picture enclosed). The sender recommended to use sulfamerazine and we have treated them 2x and we are not sure they are all recovering. Does anyone have any experience with P. waltl diseases and could give some input on this? Any input would be greatly appreciated! Thank you.
