Bicolor

A bicolor guppy is selected for two clearly noticeable colors, usually with contrast between the body and tail or between different sections of the fins. The term can be used broadly in the aquarium trade and more narrowly in show contexts, where color coverage, boundaries, and balance may be judged. Bicolor guppies may share genetics with delta, half-black, mosaic, or other named strains depending on the line.

Keeping bicolor guppies is straightforward when the line is healthy, but maintaining the pattern across generations takes selective breeding. Fry should be grown out long enough to see which males and females carry the desired contrast, and weak color separation may appear if unrelated strains are mixed casually. Buyers should look for active fish with clean fins and balanced bodies, not only the strongest color split in a sales tank.
