I believe what you have is called Lucky Bamboo(Dracaena Sanderiana), which is not a true bamboo at all.

I have two that were given to me as gifts, and they have both been doing just fine inside my kitchen window. They get NO direct sunlight, and the blind stays closed most of the time, so they can do well in very low light. All that I have ever done to them, is give them water, when needed. I give them wellwater, from my own well. City water has chemicals that may be harmful to it. I would recommend giving it rainwater or let the tap water stand in a pot for a day or so before watering with it.

Good Luck And Merry Christmas

Could I use aquarium water to water it? Apparently aquarium water is good for gardens.

I don't think that it would hurt it. I still prefer my wellwater since I know that it has no chemicals in it. I used rainwater once, and it started turning the rocks green, so there must have been some type of algae in it, which you might also get from aquarium water, but it shouldn't hurt the plant, although I can't confirm that from experience.
