I like the idea of having zoo challenges, and when starting a zoo it sure helps a bit to get a few thousand dollars for completing challenges.
But quickly the challenges loose interest, either because they are too "easy" and are achieved without even trying to get them, or because they are "hard" (meaning I would need to focus on them to get them... but why would I do that for a reward of 1000$ when I have already more than 400K available?)
In the end, and even if I like the idea, I end up ignoring them except when I get a reward notification. I think the rewards should be adjusted to the difficulty of the challenge (maybe a small amount of CC for hard challenges) to encourage us to complete them.
