Bought this for my large aquarium and it’s been thriving for over six months. The color is vibrant and it doesn’t bother other fish. Just make sure the tank is big enough since it grows quite large.

It’s a unique addition to the tank. The fish looks impressive and stays calm. I noticed it occasionally eats small fish that fit in its mouth, but nothing aggressive.

Great choice for a large aquarium. It’s peaceful and maintains its bright colors even after several months. Easy to care for once the tank size is confirmed.
