axolotls usually only breed twice a year winter, and summer this is beacuase of water temp change. our house are usually hot in the winters because we turn up the heat and cooler in the summer because we turn on the air so the years are opposite . but if u could control the temp in ur tank you could make them breed anytime, for example i got my females rlly fat so they would have alot of eggs inside of them then i turned the temp down with a chiller for a couple of days and i have 300 eggs i only keep 130 and 120 are healthy to this day, they are just developing the back legs
