There is no single superior morph. At the moment the most expensive pacman that I've seen are the Mutants. These are random frogs born from the samuria blue line that are unique. As far as pricing goes, there is no set price. Morph pricing changes often, just because your samurai blue is a price this year, the price can change the next year.

Fantasy frogs are not a naturally occurring frog and can not breed. They are a hybrid between two different species of pacman and are sterile.

As far as making actual money from breeding, all I know is that it is hard. Breeding takes alot of space and can be costly. I breed chorus frogs once and those young frogs take alot of food and time to be healthy! Taking care of tadpoles and then baby frogs takes alot of attention if you want to be successful! Cleanliness should be a priority. Expect to lose a few frogs too, not everything makes it in the wild, and even if you give them a grade A habitat some times it doesn't work! Breeding to turn a profit takes alot of work!
