Guppy breeding is one of my hobbies. There is a saying "Start with guppy, end with guppy". Guppies are often a starter fish for aquarist because they are beautiful, cheap, easily available, and hardy. With time, the aquarist then divert thier attention to other fishes like goldfish, betta, angel, chichlid, tetra, arowana, etc etc. However, as years go by, as one notice complexity of guppy breeding, he/she will be addicted to the fish again.
The beauty of guppy breeding is the complexity in its genetic. The genetic coding of guppy is so complex that no one can or will ever claim he knows it all. Why guppy breeding is so interesting for me is, not only I can improve a quality of my guppy by various breeding method, I can also create a new strain of guppy.
These photos show one of my albino full red guppy that I am trying to improve. Although this albino full red guppy has smaller tail and smaller tail angle then my the other line, its larger size and active trait is what I like and will like to cross with my the other line.
