Keeping dozens of baby axolotls alive is a lot of work.
And yet the parent axolotls seem to do it effortlessly. (Yes I know, they're probably independent within 15 minutes after birth, but I had to be contrary.)
Axolotls don't care for their young and will eat them if they encounter them before they reach adulthood, plus they lay up to several thousand eggs over their lifetime so that a handful might survive to adulthood, while I'm trying to get a rather higher survival rate. The hardest part is feeding them; they have voracious appetites and will only eat live food for the first 6 weeks, so I've been culturing brine shrimp, daphnia, microworms and fruit flies to feed to them.
