What makes a neon tetra lose its color?
Several reasons can make your neon tetra dull and lose its color. Here we list some of the possible reasons that can cause your fish to lose its vibrant color rays:
Neon tetra fish have a habit of living in school and can survive well only when they are part of any group. These fishes tend to stick to school instead of swimming solo. So being alone in the aquarium can stress them. And, stress is enough reason to make your fish dull and lose its color.
Improper cycled aquarium
Though neon tetras are hardy fish that can survive up to ten years, but improper water chemistry in the aquarium can make your fish dull. These fishes excrete ammonia that is toxic for your fish. If they are not removed or converted into nitrite by some bacteria, it can harm your neon tetra, and you can observe slow changes in their color.
Illuminated water tank
Neon tetra fish tend to live in a shady place with lots of plants. In the case when your aquarium tank is brightly illuminated and has very few plantings, it may stress your fish out. This is another reason for stress that can cause your neon tetra to fade its color.
