The Borneo Python Eel is a striking addition to my aquarium. It moves gracefully and blends well with the other fish. I’ve kept it for six months and it’s remained healthy with no signs of stress. The water parameters are stable, and it’s active during the day and night.

First time keeping a eel, and this one is a real eye-catcher. It’s not aggressive and doesn’t bother the other fish. I’ve maintained a consistent temperature and pH, and it’s been thriving.
