The Siamese Algae Eater is a great fish for the community aquarium. It prefers a planted aquarium with many broad-leaved plants on which it can rest on. It also requires these plants and rocks for grazing algae. This species can be kept with a variety of tank mates including more passive community fish.

Unfortunately, the breeding habits of the Siamese Algae Eater have not been documented.

An omnivore, the Siamese Algae Eater is not a particularly finicky eater, and is the ideal candidate for eating algae off of live plant leaves. Ideal foods should consist of a high quality flake food, freeze-dried bloodworms or tubifex, and pelleted foods, as well as vegetable-based foods.

Approximate Purchase Size: 1-1/4″ to 2-1/2″
