I recently went to the lfs and saw they were selling 4" bamboo for fish tanks. They also put larger potted peices in many of their tanks. I thought bamboo was not aquatic Would putting bamboo in a tank have negative affects?
A lot of times the bamboo they sell isn't really bamboo, (it's called lucky bamboo but it's real name is: Dracaena sanderiana) but it's still not supposed to be completely submerged. It will eventually rot. Either way, it doesn't belong in an aquarium. It would work well in a separate sump used as a plant filter though.
