Why do neon tetras die easily?

Neon tetras die easily because they are easily stressed and required specific living conditions. You can prevent your neon tetras from dying by keeping a minimum of six neon tetras in your fish tank and making sure they have the right food, PH level, water temperature, tank size, and lighting.

In addition, neon tetras have lifespans of up to ten years but can easily die because of the wrong tank size, disease, stress, and the wrong water conditions. Make sure your fish friends have a good environment, and they will live for up to 5–10 years.
