I have read that bristlenose plecos add a lot of waste to the tank. That is not very specific. When you add one to a community tank, is there a noticeable increase in waste? Are they really nasty poopers or something? They are so interesting looking, and I would really like to add one to my tank as the algae eater / weird looking guy in there. But would like some insight before I buy. Thank you for your info.
