Hi everyone! I was given a small bamboo plant as a gift 2 years ago, and it did alright for a while, although it hasn't grown much if at all. I'm a college student, so last year I left it at home and asked my family to take care of it for me. I'm not sure what they did/didn't do to it, but when I came back for the summer, the leaves weren't looking too great. Some of them were very pale, and a few others were turning brown at the end. Another one was just dead. I took it with me this year to keep an eye on it, but the leaves haven't really recovered and I'm not sure what to do. I don't actually know what kind of bamboo it is, but it's very small and it's planted in a small glass container full of pebbles, and I was told that all I needed to do for it was to keep the container full of water and clean it every once in a while. I'm not sure how accurate that advice was and I'm a bit of a beginner when it comes to plant care, so if anyone could help me out it would be appreciated!! Here are some pictures:
