lately my pleco has been eating the rough fibers of of my plant bulb and is ruining them i was wondering it perhaps anyone knows of a nice alterative to having my pleco ruin my plant bulbs.i haven't been able to get him some good wood lately and nor zucchinni either,but i will get him some more soon.he really seems to like the rough fibers of the plant bulbs and i was hoping someone knows of a good form of fiberous material that i may offer my pleco.
