Bushy nosed plecos will eat any driftwood in your tanks. That's why they spend so much time on them. They sometimes bypass the algae on the tanks to favor the driftwood. I took all mine out I just have stacked slate pcs held up by to other pcs of slate. Mine is always upside down under it but cleans my tank walls and decorations better since I remove the driftwood.
Wow, I have never seen my bn do that. Yours is beautiful by the way =P
@eileen: Umm...this could be outdated info, but when I was researching them before I got mine, most websites/caresheets recommended having driftwood for a bn to rasp on.
