You have listed so many fish...
Why don't you chill for a second, collect yourself, go through the list and think about which ones you can hold when they reach their max sizes.
Then look up how hard breeding is for them, and see what they run for at 1", 2" and so on..
Then go through your list, and number them.. 1 easiest and go up.. larger the number harder to breed etc..
Then try your hand at maybe 2 different kinds, and see how that works to start.
