I bought this fish for my 150-gallon tank and it has been thriving. It’s active and bold, which is exactly what I wanted. The XL size fits well in the tank and it’s easy to handle for a beginner. Just make sure you have plenty of space and no small fish around.

The fish arrived healthy and looks vibrant. It’s aggressive, so I made sure to keep it in a large tank with open space. It’s not suitable for a small setup, but in a proper environment, it’s a striking addition.

I expected more color variation, but the fish is solid. It’s active and needs a lot of room. I’ve had to adjust my tank layout to avoid conflicts with other fish. Still, it’s a good choice for a beginner with a large tank.
