So I've had a few BNP mainly the Albino variation. I've had males and females, I've noticed for such a small fish their somewhat territorial. I've seen him take on my Angelfish if they show interest in his food. Mainly just seen them take on larger fish. I've noticed that they REALLY like their space. I have 1 in a 65 gal and I've noticed him gaining quite a bit of territory. In the beginning he was really good with my Panda Corys, Now he's just become this Brute that chases everyone away from their food. He has to try a little bit of everything! But definitely lacks that sharing factor. I'm thinking about putting him back down in my 30gal where he wont have as many tank-mates but still have reasonable amount of territory. He's also taking a real liking to my melon plant and has proceeded to suck a large amount of the like pigment out of the leaves. Brutus is out of control. I feel he has enough to rasp on between the different plants and wood but he constantly goes to this melon plant. Does anyone else have pushy bristlenose's? I had a Sailfin Pleco a while back that I really adored and he was the most gentle fish you could ever meet, quite the opposite of the BNP's I've had.
