Question: Sex

[toffeebonbon]

How can you tell what sex your Axxie is?

My is a two yr old wild type.

He has two sort of mound at the base of his tail? does this mean he is a boy?

Axolotls become sexually mature once they are about a year old.
Males will have a pronounced bump in the cloacal region (that's underneath, between the hind legs, in case you're wondering).
Males will also tend to be skinnier and have longer tails than females. Females usually have shorter, wider heads than males. Also, the female's belly will appear to "get fat" as she begins producing eggs.
