Nice start! I liked the shop items, and the option to go for different 'builds'. I did find it a bit hard to manage my money though - going for those builds was tough when all the fish had the same body shape (with obvious differences in size and speed). If you worked on the game more, would you consider adding a few new minigames or changing up the body shapes a bit to help play into the 'builds'? Not like all exotic fish need to be shaped differently, but I think it'd be a bit more fun if you could find what you were looking for (and maybe add a timer to discourage just waiting for them). Good submission!
