I have one, (Harry the hoover) and he lives up to his name. He is also very comical. I also have Otto and they are compatible no problem.
The other advantage to the bristlenose is they do not grow too big (up to 5"). I would recommend however if you do go for bristlenose that you only get one, although they get on with Otto if you have more that one of his own kind they are ok as babies but when they get bigger they will fight over territory.
