I bought this 4-pack for my community tank and it’s been a great addition. The fish are active and colorful. I kept two males and four females, and they seem to get along well. Only had a minor chase incident between males, which I managed by adding more plants for hiding spots.

The fish arrived healthy and looked vibrant. I followed the gender ratio advice and now have a balanced group. They swim together nicely and stay calm in the tank. A little more space would be ideal for a larger group.

Great value for the price. The green coloration is bright and the fish are very active. I’ve kept them for over three months and they’ve grown steadily. I added a few floating plants to reduce male aggression and it helped a lot.
