Bamboo In An Aquarium? Didn't Know They Would Grow Like That

Ok, I am miss leading you with the title, since the kind of "bamboo" that I am referring to isn't technically bamboo. However in my defense I just found this out myself.   They are Dracaena sanderaina,  I did know that they can be grown in soil. I have bought and killed many.  But when we were getting plants for our fish tank my Husband could not resist. 



                          I know the picture sucks but its hard to get a good one with the flash and without, hopefully I will get a better one soon.

We have had it for quite a while now and so far its growing good, not to much
new" growth.  I call it a win because it isn't dead yet.  But I made a boo boo and broke a branch off during a tank cleaning and now the fish are eating at it like crazy.  Its not the end of them though, their is three stalks and only the one is being picked at so I am only expecting to lose that one.
I tried to save the branch that broke off but that did not work.
