Editing Neon tetra (section)

==Description==
The neon tetra has a light-blue back over a silver-white [[abdomen]]. The fish is characterized by an [[iridescent]] blue horizontal stripe along each side of the fish from its nose to the base of the [[adipose fin]], and an iridescent red stripe that begins at the middle of the body and extends posteriorly to the base of the [[caudal fin]]. The fish is partially transparent (including fins) except for these markings. [[Sexual dimorphism]] is slight, with the female having a slightly larger belly, and a bent iridescent stripe rather than the male's straight stripe.  During the night, the blue and red become gray or black as the fish rests. It reactivates once it becomes active in the morning.<ref>{{Cite web |url=https://www.aquariumnexus.com/neon-tetras-lose-color/

}}</ref> This peculiar change is due to the neon tetras capacity to change the color of its iridescent stripe in response to lighting conditions. In a light-adapted state it is blue-green, likewise in a dark-adapted state its color changes to indigo. This change is produced by guanine crystals in their cells that reflect light. The neon tetra grows to approximately {{cvt|4|cm}} in overall length.<ref>{{Cite web |url=https://aquariumtidings.com/neon-tetra/
