I have to add that the bushy nose plecos that I have had are good except for:
any large leaved plant such as the large amazons and java fern.
to wit, they absolutely kill these leaves. They scrape them down to the skeleton and the leaf is useless. Cut it back and they will regrow, but they get EVERY leaf on the plant, and you end up cutting it down to nothing as they look UGLY.
I like the fish, but they wreak havoc for me on these types of leaves.
Tried to do the same to my A. barteri, but they were too tough.
Leaves all else alone and does eat algae.....
That is MY experience, which apparently differs from all others LOL
I have only one BNP and he does this to EVERY large leaf, to the point where I can either have the fish or the plant, NOT YET BOTH.
Last two fish behaved the same way.
