I was thinking about adding some of that freshwater bamboo you always see at fish stores to my 55g... Now I've been hearing that that it's a fully submersable plant from some people and that the top of it needs to be out of the water from other people... I was wondering if anyone could clear this up for me and anything else that would be beneficial to know about keeping bamboo in a freshwater 55g tank, like how much lighting, what type of gravel, do I need a CO2 bubbler,...etc.
