my strategy is jus to keeping breeding fish and jus keep trying. this is wat i do: 1st, finda kind of fish that is not very eazy to die n sells for like $30,$40. keep breeding them (and selling!) and keep researching and buy all the things u think u might need. once u think u can start finding mage fish,u start buying eggs n breed a lot. although i still newb n only found 12 species, i earn quite a lot of money but sooner or later u'll start getting the idea. Good luck to all playing LDW games!!!
