The Neon Tetra

Scientific name: Paracheirodon innesi
Minimal tank size: N/A
Max growth: 1 inch
Special requirements: Keep in pairs at minimum.

Keep two neons per tank at a minimum.Everybody loves the neon tetra. And most fish keepers have enjoyed a pair or a school of these fish in their tank at one time. They are bright and colorful, and when amassed in a large school, they are breathtaking.

In my experience, neon tetras are much hardier than their counterparts, the cardinal tetra. They require a cycled tank free of ammonia and nitrite fluctuations, and they are best kept in numbers. Seven is a good school, while three can work very well in smaller tanks. Combining a school of neons with other similar characins like black neons or glowlights can really add a lot to your tank.

Neons are susceptible to neon tetra disease, a fatal malady. Symptoms are a whiting or pinking out of their red stripe. This is highly contagious so remove the afflicted fish at once, either to quarantine or put down.
