FeedingIt is thought that elements in bogwood, particularly lignin, may form an essential part of Bristlenose diet. Certainly they have the immensely long guts common to vegetarians, and although they fall avidly on the occasional meal of live food or prawns, the bulk of their diet must be composed of vegetable matter. If a high protein diet is fed constantly, then they will become prone to stomach disorders. Vegetable roughage keeps the gut in working order, and bogwood is a valuable addition to this.
FurnitureIn the aquarium they prefer a strong water current with lots of oxygen, and require plenty of hiding places. Bogwood is ideal for this, as it is not only attractive to look at and provides plenty of shelter. Although they are vegetarian, they do not feed on water plants either naturally or in the aquarium, and your treasured collection of cryptocorynes will not only remain uneaten, but the Bristlenose will carefully and gently graze each leaf, removing any covering of algae that may form.
CompatibilityThey are gentle and unassuming fish, and can be kept in community tanks with the most timid of inhabitants. Even tiny fry will be left unharmed once free-swimming.
Suggested TankmatesAppropriate with most community fish that aren't overly big or aggressive.
BreedingUnreported.
