About

The butterfly pattern is one of the most prized in show-quality bettas, requiring a clean, defined border between the body colour and the fin colour — ideally a 50/50 split. Show judges evaluate the sharpness of this transition. Butterfly bettas come in a wide range of base colour combinations.

Care Guide

Water: 26-30°C, pH 6.0-7.5, soft to medium hardness — optimal conditions preserve the pattern clarity. Tank: minimum 20L, planted; good lighting to showcase the dramatic two-tone pattern. Feeding: carnivore — betta pellets, frozen bloodworm, brine shrimp; twice daily. Behaviour: males aggressive to own species — one per tank. Compatibility: peaceful with most community fish; excellent display species.
