I kept this fish in a 55-gallon tank with other active species. It’s quite striking with its silver sheen and sharp teeth. It does need a strong filter and regular feeding of frozen foods. Not aggressive toward tank mates as long as they are larger and active.

The Saber Tooth Payara Tetra looks amazing in the tank. I’ve had it for over a year and it’s still active and healthy. The metallic scales catch the light well. I feed it frozen brine shrimp and daphnia daily.

It’s a bold-looking fish, but I noticed it occasionally targets smaller fish. I had to adjust my tank setup to include larger, more active species. It’s not for small tanks or beginners.
