Hey everyone, been quite a while since I was on this forum. Good to check back in.
I have two Alpine newts, Apaunus type. By this time they are just over a year old. I've increased photo period by 2 hours and their tank temperature has risen from 12.7 C to about 18 C. (55-65 F). I was wondering what veteran alpine owners use as key sex determinates for this species.
Here's what I know: Females tend to be larger, males have a larger cloaca, males will be brighter in mating season and will grow a crest. Are there any other signs of sex, especially in younger newts like mine?
The main differences I can see between my two are these: one is much larger, eats more, and has a much wider head. This large one also has a broad tail, tapered at both ends. The other newt is not as plump, eats less, has a more narrow face and body shape; it also has a longer tail in proportion to body that is starting to broaden. This smaller one has a more vivid white coloration bar between its blue back and orange belly. I'm talking about the white stripe that runs from the lower lip along the side of the animal. I really haven't gotten around to a close cloaca examination so I can't say much about that. Neither of the two are showing signs of a ridge along the back yet although one or both have the orange bar running down their spine.
Does it sound like I have two different sexes here or are these both female? I know it can take up to three years for newts to reach sexual maturity but this is what I've been noticing as of late.
