bristle noes plecos are great i have one (bob). i got him for like 8 bucks. he was like 2 inches. all in all, a pretty good eater. doesn't bother my plants. although, you want to addd these guys after your plants have had enough time to root them selves. BOB tends to just swim through patches of plants, like a bull doser. definatley and algae eater. i've caught bob up near my power filter suckin away. imho, buy him!!! interesting little critter. also, get a red light bulb and watch him at night. very very active at night.
