The betta arrived quickly and looked healthy. The mask blue mustard color is vibrant and the halfmoon fin is very striking. It’s active and stays calm in its tank. I’m happy with the purchase.

Received the betta in perfect condition. The halfmoon fin is well developed and the fish is active. I’ve kept it in a 5-gallon tank with a heater and it’s thriving.
