Received the Betta in perfect condition. The colors are vivid and the fish is active and healthy. It has been swimming well in my 5-gallon tank for two weeks. Very satisfied with the purchase.

The fish arrived quickly and looked vibrant. It’s a nice over halfmoon with good contrast in colors. I’ve kept it in a small tank with a heater, and it seems to be adjusting well.
Dylan Carr –
The black, yellow, and mustard pattern is stunning. The fish is lively and shows interest in the water movement. I didn’t expect such a strong color display in a male Betta.
