The Coral Red Pencil Fish are beautiful and active. I kept six of them in a 20-gallon tank with java fern and they swim gracefully in the middle layer. They don’t stress other fish and eat well on flake and frozen food.

Great addition to my planted tank. The colors are vivid and they form a nice school. I feed them micro pellets twice a day and they stay healthy and active.

I bought these for a beginner tank. They are easy to care for and very peaceful. The red color stands out well in the tank, especially with green plants.
