Koi Betta Roundtail

The Koi Betta is a highly sought color variation that comes in roundtail (plakat) and veil tail fins. The koi betta has a variable color pattern that features red, white, and black and is named after the color pattern of the sanke and showa koi found in ponds. No two koi bettas have the same pattern, but all koi bettas are truly rare. The roundtail shape is prized by not very nice Thai who prefer this body type for betta fighting; the body tends to be stronger and the tail is harder to grab.

Quick Facts

Care Guide

Tank setup: Give him a heater (bettas are tropical fish), a gentle filter and live or silk plants. Plakats are active swimmers and like room to patrol. Keep a lid on the tank and leave a gap of air under it, since bettas breathe from the surface.

Feeding: Feed a few betta pellets or a pinch of flake once or twice a day. Bettas overeat easily, so small meals are best. They also enjoy frozen bloodworms.

Tankmates: Never keep two male bettas together. Plakats are among the boldest bettas, so they do best alone or with sturdy, peaceful fish like corydoras and snails. Avoid fin-nippers and other labyrinth fish.

Good to know: Koi and galaxy bettas carry the "marble" gene, so their colors and patterns can shift throughout their lives. No two look alike for long. Short plakat fins make them sturdy, active swimmers.
