Crowntail Betta The crowntail betta, or rooster tail betta, is a fish is a popular betta variation and really looks amazing when displaying against another male (just let him see his reflection in a mirror). The fins look like the crown of a rooster. The webbing between the rays is significantly reduced, making the spikes appear more prominent and giving the tail fin a crown-like appearance.  Crowntails might look flashier than bettas of other fin types, but all betta fish require the same care. Feed your Betta fish food once a day, but don't give him more than he can eat in 5 minutes.  The best environment for the Crowntail Betta fish is a well-filtered aquarium that holds a steady temperature of between 70° and 80°F.  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. If you are looking for a specific coloration, add a note to the order or simply allow us to choose one of our favorites for you!
