I have been playing Fish Tycoon, and couldn't find a guide that had all the information that I wanted, so I have started making one of my own. It is a WORK IN PROGRESS! I will add more whenever I create new combos. My chart is color coded for ease of use, and has LOTS of information. You can find it here: B's Fish Tycoon Breed Chart
Check back often for updates.

Added some more fin & body combos. Too bad it's kinda slow going right now. Will have more soon.
