A fish counter would be a fairly easy addition. But, remember you guys... Last Day of Work is DONE WORKING! They are not going to do ANYTHING to this game! This game is already nearly 10 years old and, the amount of sales is only due to new platforms coming out and, people putting the game on them. (smart phone, I pad etc) As for adding more tanks. Part of the games difficulty is deciding which fish to keep and, which you can discard. It's called strategy. Sure with 5 or 6 tanks you could keep two of everything. But, that would drastically change the dynamics of the game. YOU COULD develop your own fish breeding game with all the things you want. There ya go! What a great ideer! BUT, it would never be as good as FISH TYCOON! Oh, by the way,... I just bred all of the special fish in 1 DAY!
