I bought a group of Forktail Blue-eyes for my 30-gallon planted tank. They’ve been active and colorful since arrival. The blue irises stand out in the tank and they seem to get along well with my other community fish. Easy to feed and don’t stress the plants. A great addition to a freshwater setup.

The fish arrived healthy and were active right away. I kept them in a group of six with other peaceful species. They swim in schools and add a nice visual appeal. I appreciate how they don’t compete for food or damage the plants.

Perfect for a planted aquarium. The blue eyes are striking and the fish are very calm. I’ve had them for three months and they’ve never shown signs of aggression. They thrive in the soft, nutrient-rich water of my tank.
