Question: axolotl how to tell gender?
Answer: The most reliable way to tell whether your axolotl is male or female, is to look at their cloaca (vent). The male's cloaca is swollen, while the female's has only a tiny bump, if one at all. When lighter coloured axolotls (albino, golden and leucistics) reach sexual maturity, their toe tips turn dark brown/black.
