A school of neon tetras for a calm aquarium

We had these neon tetras in our small home aquarium for about a year. We kept them in a small group because they feel much calmer in a school. When the lights come on in the morning, they first gather near the plants and then begin swimming throughout the aquarium. Their blue and red stripes look especially beautiful when the light reflects off the water. They are very peaceful and have never shown aggression towards other species. We fed them small dry food and occasionally added frozen food. We've decided to reduce the number of fish in the aquarium because we plan to change its design, so we're looking for someone who can add this school to our existing aquarium.
