The Blue King Tetras are incredibly colorful and active. I kept them in a 10-gallon tank with live plants and a group of five. They swim together in a school and look beautiful. Easy to care for and very peaceful.

These fish are a great addition to a community tank. They don’t stress other fish and enjoy the plants. I’ve had them for three months and they’re still vibrant and active.
