Growing bamboo in clear glass may allow more algae and other things you don't want to develop in the water. Otherwise, it is fine. I have heard of people growing the plants in fish tanks and other clear containers. You may have to take more steps to keep the water clean. If the top of the stalk is yellow, you can cut that part off. This will stop the spread if the stalk is dying. It may be just overexposed in that area. If you do not wish to cut it off, you can see if the yellow is continuing to spread down the stalk. If not, it can be ok to leave it. If it looks better without it, they why not? The black roots do not sound good. If the roots are red, that is ok. Black roots mean the plant is dying. There is some opportunity for the plant to regrow the roots. Your last option, if you think the top and the bottom of the plants are rotting, is to cut the plant up. You can cut the healthy part of the stems into sections, dip the sections into root hormone, and place them into soil or water to root! Here is a link that might be useful: See the root color?

Okay that was just weird , LOL !!

Amyly Ann, here are some care instructions on found online. Lets not even think about fertilizer right now, the plant doesn't need it yet as it has to recover from all the messing around were are doing to it, and it is in new soil so it is fine on fertilizer right now. http://houseplants.about.com/od/typesofhouseplants/a/LuckyBamboo.htm Caring for Your Lucky Bamboo Light: Lucky bamboo prefer bright, filtered sunlight, such as found under a rainforest canopy. Avoid direct sunlight as it will scorch the leaves. They are more tolerant of too little light than too much. If the plant begins to stretch, however, or the green fades, provide more light. Temperature: Lucky bamboo likes warmer temperatures of between 65ºF and 90ºF. Do not place the plants in front of air conditioning or heating vents. Potting Media: In addition to water, lucky bamboo can be grown in a well-drained, rich potting soil. Keep the soil moist, but not soaking. Water as you would any Dracaena species. The Dracaena genus has provided some of the sturdiest houseplants available today, including the every-popular D. deremensis. These plants, which are native to Africa, have been used as houseplants since at least the mid-19th century and are still popular because they possess the single most important quality in a houseplant: they’re pretty and fairly hard to kill. D. deremensis work as single windowsill plants or as part of a mixed group, with their various leaf patterns complementing and overlapping one another. Growing Conditions: Light: Low light is fine, but they like it a little brighter. New leaves will narrow if there isn’t enough light. Water: Keep evenly moist, although if you have to err, do so on the dry side. (But keeping it too dry will result in brown leaf tips.) Use non-fluoridated water as they are sensitive to fluoride. Temperature: Keep above 50ºF if possible. They do best in the mid-70ºs to low 80ºs. Soil: Loose, well-drained potting mix. Fertilizer: During growing, fertilizer with slow-release fertilizer or use a 20-20-20 liquid fertilizer at half-strength every month. Propagation: They root readily from cuttings. Push tip cuttings into warm soil and keep moist. They will usually root readily without use of rooting hormone. They should root within a month. Repotting: Repot annually into larger pots with fresh, free-draining potting soil. Grower's Tips: D. deremensis is a great plant for low-light conditions, but beware of low humidity. If the humidity drops below 40 percent for an extended time, the tips of the leaves can turn brown. Try misting the plant every day to provide humidity. It’s also sensitive to fluoride and excessive salts, so try to use nonfluoridated water and flush monthly to remove fertilizer salts. Growth may cease completely below 70ºF, but will resume when warmer weather returns. Iron deficiency can result in yellowing leaves between the veins—treat with an iron drench. They are susceptible to thrips and mealybugs.

the little guy isn't looking so good now.
