Siamese Algae Eater

Siamese Algae Eater (Crossocheilus oblongus) is a highly effective algae eating fish known for its sleek body and peaceful nature. Our Siamese algae eaters for sale grow to around 15cm, making them a great addition to medium and larger aquariums, especially those with algae problems, as they help keep tanks clean by grazing on various types of algae.

Location

Native to Southeast Asia, the Siamese Algae Eater is found in clear, fast flowing rivers and streams in countries like Thailand, Cambodia, and Vietnam. It thrives in warm, tropical waters with abundant vegetation.

Diet

While it primarily feeds on algae, the Siamese Algae Eater also benefits from a varied diet that includes sinking pellets, live or frozen foods such as brine shrimp, and vegetables like spinach or courgette.

Care

Siamese Algae Eaters thrive in water temperatures between 24 and 28°C. They are peaceful, non-territorial fish that do well in community tanks with other calm species, but should be kept with plenty of space to swim. Adult shrimp such as amano shrimp are usually safe with them, although baby shrimp may be eaten.

Habitat

In the wild, these fish live in fast flowing rivers and streams with clear, slightly acidic water. Recreate this habitat by providing plants, rocks, and a good filtration system to maintain water flow and quality in your aquarium.

Breeding

Breeding Siamese Algae Eaters in home aquariums is very rare, and almost all are bred commercially on fish farms.
