Yikes!! Thats good to know. I had a pleco do that to my Discus before....H5N1;845097;845097 said:Becareful of putting pleco and bichir together. There is chance that the pleco will suck on the bichir's skin. I once kept a 6" pleco with my 10" ornate for quite sometime. But one day i found the body of the ornate all bleeding with the skin gone. And saw the pleco kept trying to suck on the ornate. The pleco left the tank right away.
