What a question. If America politics depends on this kind of question, it's no wonder you're fff'd (we're fff'd).

two rats two tapeworms
...do I gotta build a tank big enough for the freshwater fish? ... or should it be salt water?
... let's see, should I include all extinct species and all species not yet developed? How about the pre-homo sapiens, the hominids?
And how do I feed all the carnivorous animals, should I include more than 2 of some species? I got it, I'll bring them all and let the predators eat what they will, then the rest will survive the flood. Survival of the fittest... hmmm... catchy phrase. It'll work, I think.
