Thanks for the help! I have a real bamboo shoot that I’ve been growing in a cup of water for a while, so I think I’ll give it a tryFahn said:Bamboo itself contains compounds that break down into hydrogen cyanide when plant cells are disrupted. The amount may be negligible but it is wise not to eat too much uncooked bamboo if used in certain Asian dishes.
In your aquarium I wouldn't worry, but not sure how bamboo would grow with it's roots submerged in water.
Now the "lucky bamboo" you see for sale isn't true bamboo, but is a species of Dracaena. This plant will grow just fine as long as you don't submerge the whole thing, just the roots.
