it has to peak out? i was thinking about growing one inside the tank as a part of a live plant decor and mount a uv light on the canopy in replace of the sun.
Bamboos are not true aquatic plants. If you dip the whole thing into water, It would....."drown"? I cant find another word to describe it. And do not use UV light, you would kill the bamboo and the radiation may harm you and the fishes.
we have a 3' piece of bamboo stalk that we have suction cupped to the glass so one of the turtle tanks can have a resting spot (place to grab on). It's turning a nice goldish color as time goes on. Going to find a bigger piece outside to cut down and mask the filter intake on the fx5 in another tank. You can also hollow it out by making a pointy stick out of anything metal (like a long skewer) and making it hot w/lighter than hollowing it out to hide air tubing in.
