I often just fail until it gets embarrassingly or super inconveniently bad. My only strategy that was ever even a little helpful was breaking the task into tiny micro 5 minute tasks and writing them all down, and doing a few of those at a time. I had adhd though, and am hoping medication will help with that (so far it has a bit).
But captive axolotls are not really true axolotls, they are different from the near extinct wild ones (they have a bit of tiger salamander mixed in). And this really only holds true if people breed their wild-caught aquatic animals - otherwise you are just grabbing a living being from its home and putting it in a tiny cage. There is a place for wild caught fish, but it doesn’t seem very kind to remove them from their habitat to languish in an aquarium for a fraction of their normal lifespan, which is undoubtedly what happens a lot…
