I added a school of six Black Emperor Tetras to my 20-gallon tank. They are very active and their deep black color makes the tank look vibrant. Easy to maintain and they don’t stress other fish. Great for beginners.

The fish arrived healthy and seem to be adjusting well. I feed them a mix of flakes and live foods. They swim together in a coordinated way, which is very pleasing to watch.

Perfect for a community tank. They don’t compete with other fish and stay calm even during water changes. I’ve had them for over a year and they’re still lively and colorful.
