The fishes arent that "real" in appearance; as a matter of fact, their tails are the only mobile part of the whole fish while the stiff body moves across the screen like a 2-D figure. There isnt much too do other than grow your fish, keep your favorite ones, and then sell the rest for more money. You then use that money to buy more fish, which you end up selling in the end for yet more money or just fill up your tank too spend hours watching some 2-D action (no love making, but microscopic fish randomly appear in which to signify that there has been "invisible" love making). The variety of the fishes are a bit limited and the fishing mini-game is somewhat fun, but hey, what can you expect for a dollar? Overall, I think you should buy this app only if you have extra money on you.......or if you feel obligated to donate in the hopes of this app becoming a bit more "active" in animation and market.
