The rainbow shark is colorful and active, adding a lot of life to my tank. I’ve kept it for six months and it’s still healthy. Just make sure to have compatible tank mates since it can get aggressive as it grows.

Beautiful fish with vibrant red fins. It’s peaceful in a well-established tank, but I noticed it nipping at smaller fish after a few months. I added larger species to avoid issues.

Great addition to my community tank. The fish is lively and stays active throughout the day. I maintain the pH and temperature within the recommended range and it thrives.
