Dangerous mix, plecos often develop a taste for slime leaving the fish prone to infection and disease. Slow moving fish such as bichirs won't fight back either, they'll just take it and then regret it when theyre dead.
i had my ornate in with my L-200 for 8 months before the pleco tried to suck on the bichir. then i had to sperate them. i hought they were fine together, i was wrong....
i juts wouldnt risk it, bichirs r cooler than plecs newyas
its something i wouldnt recommend. might get away it if it is a albino bristlenose, but even then it might get eaten due to size. i would imagine all the other albino plecos you'd have problems with. its a nice idea, but not practical
