heres my two cents;
"the bulk of their diet must be composed of vegetable matter. If a high protein diet is fed constantly, then they will become prone to stomach disorders. Vegetable roughage keeps the gut in working order, and bogwood is a valuable addition to this.
In the aquarium they prefer a strong water current with lots of oxygen, and require plenty of hiding places. Bogwood is ideal for this, as it is not only attractive to look at and provides plenty of shelter.
They are gentle and unassuming fish, and can be kept in community tanks with the most timid of inhabitants. Even tiny fry will be left unharmed once free-swimming."

What i find with some of my smaller plec's is that if givin' plenty of hiding places they tend to be more outgoing, my suggestion to you would be that if you want to see more of the BN make sure you have lots of places for it to readly hide in.
I'v never personally had any agression tword other fish with a BN, although a couple of Clown pleco i had were very agressive, and even killed one Blue Gourami.
