The eel arrived healthy and active. It has adapted well to our 55-gallon tank. We’ve added some peaceful community fish, and the eel seems to coexist peacefully. Water parameters are stable, and it’s a beautiful addition to the tank.

We’ve had the eel for three months now. It’s very calm and doesn’t seem to chase or stress other fish. The white markings are clearly visible and quite striking. A bit shy at first, but now it swims regularly in the tank.
