Common guppies (not as much fin) can be produced in large sizes with the following adjustments to their rearing:
1. The larger the body of water, the larger the guppy.
2. The warmer the body of water, within the temperatures tolerated by guppies, the faster they grow and the larger they get.
3. Selective breeding can increase the size of guppies.
Even with all that, you will not find a guppy larger than 1.5 inches in length. Females are always larger than males.
I believe there is a species of gambusia that is larger than most guppies. (?) Mollies are another option that is larger. But who knows the thiaminase properties of those species? Mollies live, grow, and reproduce best, in slightly brackish water.
