Axolotl Eggs

egg laying
If you have been lucky enough for your axolotls to breed, congratulations! Axolotls typically lay between 150-450 eggs over the course of about two days. The eggs are individually affixed by the female onto various plants, rocks and decorations around the tank. You should try to avoid disturbing the female while she is laying. But, once she is finished, the eggs should be removed from the adult’s tank to keep them from being consumed by the adults.
Raising a full clutch of eggs to juvenile or adult size requires an immense amount of time, effort and space. A hobbyist breeder should try to limit themselves to about a dozen eggs, to ensure that you are able to give each the necessary care it needs to survive and thrive.

A shallow plastic tub with a gentle air stone, works very well for raising the eggs until they hatch. The eggs hatch best at a temperature of around 19-20°c. If the temperature is lower then 19°c the embryos within will develop more slowly. If the temperature is very much above 22°c, the eggs will be more likely to become moldy and stop developing.

Only golden albinos and white albinos will lay white eggs, other color morphs such as wild-type, leucistic or black-melanoid will lay black eggs like those pictured below. All color morphs can propagate all other color morphs as long as they have the right variety of genes. The embryos within the eggs typically begin to differentiate in color a few days before they are hatched, but you won’t be able to be certain of the color morph until the animals are juveniles.
As the eggs mature, you will be able to see the embryo of the axolotl developing. You should be able to see the embryos moving, spinning or twitching within the eggs. Eggs typically start to hatch after about 17 days. Once the eggs start to hatch it will typically take about three days before all of the eggs in that clutch are hatched.

As the axolotls hatch, you will want to remove them to a separate container. Continue here for information on how to raise hatchlings.
