I have two Chinese Browns that were hatched two years ago this month. One, the larger one, has - once reaching adulthood - always acted "male," while the smaller one has always acted "female." I attempted to vent sex both the other day, since I've found no evidence of eggs at all, and was wondering if both were male. I saw nothing indicating male in either one, but thought perhaps I hadn't opened the cloaca enough to see what I needed to see. Haven't tried again since, but was going to do so soon. Wanted them to get over the "insult" to their dignity before I tried again, LOL!
However, the last time they got their big swimming tub cleaned and fresh water in it, when the smaller one jumped in and started swimming/playing/dunking, and the larger one then got in, it looked as though the smaller one was trying to subdue and mount the larger one! The larger one immediately got out of the tub/pool/water, so I am wondering if the smaller one was just trying to defend the water as his/her own or if he/she was trying to show the other one what he/she wanted the larger one to do. Dang, that's a lot of pronouns... I hope it made sense. *sigh*
Here are the clearest pics I've ever managed to take of each of their heads, and they were from last June. This one is with the smaller one, Thunder, closest to the camera, head facing sideways, knob clearly showing.
This is with the larger one, Lightning, closest, head facing sideways, knob clearly showing.
I have been convinced they were a pair, but with no eggs again this winter/early spring, and a failed vent-sexing, then adding in the smaller one "mounting" the larger one in the water, I am now completely confused. The larger one now clearly has a thicker neck than the smaller one, too, unlike what is in the old pics. (they're not exactly hams for the camera)
Any advice? Thoughts? Opinions? Do I need brand new pics to post, or are these sufficient for asking and receiving opinions, advice, or even random thoughts?
