it counts as one bigger water park with a fish breeding cap of 20 (but you can swim between floors)

in answer to the previous reply - a new fish seems to be born every day/night cycle.... and it appears to be 1 per pair, rather than a flat rate, so if you put 4 fish in, the following dawn you'll get 2 more.....
