I added a school of six neon dwarf rainbowfish to my 10-gallon tank with live plants. They are active and colorful, and their hues brighten noticeably after a few months. Easy to maintain and don’t stress other fish. A great choice for a beginner aquarist.

The fish arrived healthy and were immediately active in the tank. They school well and look stunning in a planted nano setup. I keep them with peaceful community fish and haven’t had any issues.
