Its the narrow range of husbandry that does not work for all of them. There is husbandry that indeed works for all. You just have to be willing to support that.

Its ok to choose not to support what works for all of them. That's a choice you can make. You can also choose to support what only works for most of them. Or works for a few, etc etc.

While they are indeed individuals, their biology is the same. Cheers and best of luck
