Easy Best Exhibit Design award
When you make an exhibit, place three large rocks (which satisfy most animals, but not all --the warthog which is happier with more) and put all the foliage in one corner and a few others scattered through the exhibit but quite a bit apart. If you clump it all in one corner, once the animals are in the green bar with happiness, with thier foliage stop. Doing this with two or three exhibits will easily win you the award.
Easy fence repair
Instead of waiting for a maintenance worker, just buy the same kind of fence and replace the deteriorating part. If you are low on money, pick up the worker and move him to the fence. However, there is no guarantee he will work on it -- they will just walk away.
Easy money
Use high breedability animals, such as warthogs or velociaraptors, and make them as happy as possible. As soon as they give birth to offspring, sell them. This is useful when they start to overpopulate your cages, or if your losing money.

Stop guests from shocking themselves and cure crowding
It can be a nuisance when the guests leave because they ran into one of your electric fences. To stop this at the expense of a little money, before you make a fence for a new exhibit, outline the area with a decoration fence (which are usually at the bottom of the fence list). Make sure it is facing outwards, not towards the exhibit. Otherwise, when you make the fence too close it will build directly over the decoration fence. When you make the normal fence for the exhibit, face it inwards and they should be almost in the same location. Make sure there is a hole in the decorative fence for the entrance to the exhibit. Once this is done, not only will the guests no longer shock themselves but they also will not be crowding the animals. Note: This will not work from the inside. Even with decorative fences inside, the animals will not only be enraged but will still shock themselves by simply trampling it.
