The fish arrived healthy and active. It swims well and shows bright red fins. I have a 120-liter tank and it’s been a few weeks since adding it. It’s not aggressive yet, and I’ve placed it with compatible fish. I’m happy with the appearance and energy it brings to the tank.

The fish looks vibrant and moves around a lot. I’m cautious about tank mates since it’s territorial. I’ve added some peaceful species and it seems to coexist. The red fins stand out well in the tank.

Great addition to my aquarium. The fish is active and shows strong colouring. I keep it in a large tank with good water flow. It hasn’t shown signs of stress or aggression yet.
