Hello!

So I have 2 greater sirens that i believe are adults (24" and 26") and im interested in trying to breed them, but im not quite certain if i have a male and a female!

All i know is that the females are typically a bit wider and have a nearly flat head, as opposed to males, who have larger muscles in their head that bulge out a bit.

This description fits my sirens pretty well, but the differences are somewhat subtle. Ive attatched some photos and would love to know what you all think!

I'm certainly not an expert in greater siren breeding ;) but I thought your post deserved a reply. To my untrained eyes, the one with the blockier head appears to be male. I am less certain of the other one, but it could be a female. If you put them through a wintering cycle, you may notice the male's masseter muscles (the ones giving him that block-headed appearance) become even larger. Females should not exhibit these signs. I had a male lesser siren for several years whose head would become larger in the spring then "shrink" back down to normal in early summer.

I would say the darker colored one on top is a female, because her head is flat and her mouth is straight with her body. The bottom, lighter one is a male. His head has a bump and his mouth kind of tilts up because of the muscles in his head.

I have two lesser sirens. When I bought my second one over a year ago I was hoping when it could be sexed I would have the opposite sex to mine, so I could maybe breed. I have two boys now. It's separate tanks and no babies for me. Best of luck with yours!

    I currently have a 3 year old axolotl, he hasn't been eating for the past couple of weeks and has lost a lot of weight. Hedwig usually eats bloodworms and earthworms just fine but now he won't even stud it. I've done a water change to make his nitrate lower and his water is at a good temperature
