A few tips for care:
Light: Lucky bamboo needs to be kept in a place where there is ample amount of air flow. It prefers mild or indirect sunlight.
Watering: Ensure the root tips are dipped in water. Always prefer using purified water instead of tap water. The plant might not be capable of absorbing some elements present in tap water in your region. So, why risk it!
Other tips: The container should be washed well once a week to prevent growth of algae or bacteria. Replace the water as well, once a week. If you prefer adding pebbles in the container, make sure they are washed well too.
