We've got a lot of bamboo growing in the backyard, so I decided to try a segment of it in my pleco tank to see how it would work. I soaked it for four days before adding it to the tank. It was floating at first, but by the third day, it sunk. There was also a slimy white coating that formed on the inside and I removed it before it went into the tank. The shrimp probably would have eaten the stuff, but I didn't want to take any chances.
