The Dumbo Ear Betta, roundtail variety, is bred to showcase the extended pectoral fins (the "dumbo ears"). The roundtail is bred so that the other fins do not compete with the appearance of the pectoral fins. Roundtail dumbo ears are hardy bettas, but they can't fly.
There are many names for the particular betta color patterns, but most are variations of blue and/or red colors. Fish pictured here are representative only.

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: The big "dumbo ear" pectoral fins act like paddles, so dumbos swim a little slower. Give them gentle flow and resting spots near the surface.
