I bought a small group of Maccullochi Rainbow Fish for my 20-gallon planted tank. They are very active and add a lot of visual interest. The colors are bright and they swim together in a natural school pattern. Easy to care for and don’t stress other fish.

These fish are tiny but make a big difference in the tank’s energy. I’ve had them for three months and they’re still vibrant. They do best in a well-planted environment with gentle water flow.

The fish arrived healthy and were immediately active. I love how they move through the plants and reflect light. They’re a great addition to a community tank with tetras and corydoras.
