The Red Eye Tetras are active and colorful. They adapt well to my 20-gallon tank with stable water conditions. I feed them flakes daily and brine shrimp weekly. They stay calm with other peaceful fish and look vibrant after a few weeks.

Easy to care for and very peaceful. I keep them with neon tetras and they don’t compete for food. The red eyes stand out in the tank. Just make sure the water temperature stays within the recommended range.

Great addition to my community tank. They swim in groups and are active during the day. I maintain a stable pH and temperature, and they thrive. The only thing is they need a bit of variety in diet to stay healthy.
