From what I understand plecos can be a tad picky about water and seem to die randomly fairly often. Buggers. I have a BN as well and I don't think I've ever gone looking for him without that sinking feeling he may be dead. But he is cute. His name is Dave after the coach of the junior hockey team I have season tickets to. Why would I name him after a coach. Cause it seems like he has so little to work with (one little pleco) but he got the job done and cleared my tank of yellow algae overnight with the aid of some assistants the are Joels (otocinclus catfish).
