very nice, reminded me of my fishtank. it was quite nice to watch and discover their different behaviors and although i did not see any flocking patters, it was fun to watch them run and compete for the bits of food. the flying type reproduced so much that any food created by the bush would get instantly eaten and create one flock of nearby 'fishes'. i saw fishes that would eat other fish; some of them i'm not sure what they do but they seem to change with time.
in general just adding more stuff at random makes the money raise faster so there is no difficulty in keeping them alive or anything like that.
had to play at 90% zoom, otherwise the game window would be bigger then the browser window
