The Bristlenose Pleco has been recognized for years as the #1 best algae eating Pleco in the aquarium hobby We at Canada Guppies definitely don't disagree. Not only that but the Bristlenose Pleco doesn't get large like some others that can reach sizes of between 10 inches to a whopping 3ft in length the Bristlenose Pleco only gets 4 to 5 inches long as adults. The Bristlenose also known as the Bushynose Pleco is even quite easy to breed and keeping them is a very rewarding experience. They also come a few different colors these are the brown variety which is very popular. As adults they can be between chocolate brown to grey with white and black speckles.
