i've started much in the same way, made screenshots of all breads, some have 3 screenshots as i found out the same fish can come from different parents, which makes it all a bit confusing..i've found the magic fish without problems, quite early in the game, without the unknown chemical btw, and have found (only) 175 types of fish sofar, and i am running out of ideas for breeding ;-) i've used the chemical now and found about 20 breads with it...tiger fin is my latest discovery...
