Bicolor

Bicolor in betta fish describes a color pattern rather than a separate species or fin type. A bicolor betta has one main color on the body and a clearly different color on the fins, or a strong two-tone division across the fish. The pattern can appear on veiltail, halfmoon, plakat, crowntail, and other domestic Betta splendens forms. Show breeders usually prefer clean contrast and minimal bleeding between the body and fin colors, though pet-quality fish may be less sharply divided.

Since bicolor is visual, care depends more on fin length, body condition, and temperament than on the pattern itself. Long-finned bicolors need gentle filtration and decor that will not tear fins, while short-finned individuals tend to swim more easily. Buyers should expect some color change as young bettas mature, especially if marble genetics are present. Pairings are planned around both body color and fin color, so the label alone does not predict offspring.
