Siamese Algae Eater

Siamese Algae Eaters are prized by aquarists for their willingness to eat stubborn black beard algae that few other fish will touch, making them a go-to choice for keeping planted tanks in check. Their sleek, streamlined body and active swimming style make them fun to watch as they patrol the tank. Young individuals are generally peaceful and mix well with tankmates, though they can become a bit more assertive and territorial as they mature. Being omnivorous, they will also accept algae wafers, prepared foods, and frozen foods, making feeding straightforward. Considered beginner-friendly, they typically live 5 to 10 years and reach 10 to 15 cm as adults, making them a solid pick for both new and experienced fishkeepers.

About Siamese Algae Eater

The Siamese Algae Eater is a hardy tropical fish valued for eating black beard algae in planted tanks. Beginner-friendly, it lives 5 to 10 years and grows to 10 to 15 cm as an adult.

7 things to know before welcoming a Siamese Algae Eater

  1. 1A go-to algae eater

    It is one of the few fish known to eat black beard algae, a stubborn type many other species will not touch. This makes it a popular choice for keepers who want to maintain a clean planted tank.

  2. 2Gets more assertive with age

    Juveniles tend to be calm and easygoing, but adults can become somewhat more assertive. Keep an eye on interactions with similarly shaped tankmates as they mature.

  3. 3Easy, omnivorous diet

    Beyond algae, it will happily eat prepared flake or pellet food as well as frozen foods. This makes it easy to keep well-fed even in tanks with little algae.

  4. 4A 5 to 10 year commitment

    With proper care, Siamese Algae Eaters can live 5 to 10 years, making them a long-term addition to your tank. It is worth planning ahead for years of care before bringing one home.

  5. 5Adults reach 10 to 15 cm

    This species grows to 10 to 15 cm as an adult, larger than many small tank fish. Choose a tank size with their adult size in mind, not just how they look as juveniles.

  6. 6Active swimmers that need space

    They are active fish that like to swim throughout the tank rather than stay hidden. Aim for a layout with open swimming space alongside plants and hiding spots.

  7. 7Choosing tankmates carefully

    While considered beginner-friendly, their tendency to become more assertive with age means tankmate selection matters. Calm, similarly sized fish generally make good companions.

Frequently asked questions about Siamese Algae Eater

A.It is best known for eating black beard algae, but as an omnivore it will consume other types of algae too. Still, do not rely on algae alone; supplement with prepared or frozen foods.
Q.Can it be kept with other fish?
A.Young individuals are generally peaceful and mix well with other fish. As they mature they can become more assertive, so it is worth monitoring compatibility with similarly shaped tankmates.

A.Yes, it is generally considered beginner-friendly and fairly hardy. With basic water quality maintenance, it is a manageable fish for those new to the hobby.
Q.How big does it grow?
A.Adults typically reach 10 to 15 cm. It is a good idea to plan your tank size around their adult size rather than how they look as juveniles.
