Make a new type of fish tycoon where it has over 10,000 of fish. Include it so where you can have salt water and fresh water fish.

Have the store a hugh multi complex where you can not only have real life sharks, like great whites and such but little fish such as perch and bass. Make it so where you can buy/build a fish store. Say you start out with 50 grand that you start out a loan with, and the build on up from there. Have other stores around you, so you can put them out of business. I got more ideas for you but i dont feel like typing much more but if you guys feel like making this game i feel it would proove to inhance your game play and people would deffently buy it. =)
