I bought six ruby tetras for my 10-gallon planted tank. They’ve been active and colorful since arrival. The fish are easy to care for and don’t stress other tank mates. Water quality is key, so I do weekly water changes. Very satisfied with the purchase.

The ruby tetras arrived healthy and vibrant. I kept them in a group of six with neon tetras and they get along well. They eat flake food easily and stay active throughout the day. A nice addition to a small aquarium.
