The Siamese aquarium cleaner fish, also known as the SAE, is a popular choice among aquarium enthusiasts for its voracious appetite for algae. Native to Southeast Asia, this fish species is highly efficient in consuming various types of algae, including stubborn and hard-to-remove varieties. Its distinctive appearance, characterized by a sleek body and black horizontal stripes, adds a touch of elegance to any aquarium.

SAEs are peaceful fish that thrive in groups, so it’s recommended to keep them in pairs or small schools. They are not only excellent algae eaters but also fun to observe as they interact with their tank mates. Providing plenty of hiding spots and a balanced diet can ensure their well-being and productivity in algae control.

2. Otocinclus Catfish (Otocinclus spp.)

Otocinclus catfish, often referred to as “otos,” are adorable and diminutive algae eaters originating from South America. Their small size makes them a perfect fit for nano aquariums and community tanks alike. Otos have a penchant for grazing on diatoms and soft algae that tend to coat aquarium surfaces, plants, and decorations. Their small mouths and sucker-like lips are well-suited for meticulous cleaning tasks.

Because otos are social creatures, it’s a good idea to keep them in groups of five or more. They prefer well-established aquariums with plenty of hiding spots and a variety of surfaces to graze upon. Adding blanched vegetables, such as zucchini or cucumber, to their diet can supplement their algae consumption and ensure their overall health.

3. Amano Shrimp (Caridina multidentata)

Amano Shrimp, named after the renowned aquarist Takashi Amano, is a popular choice for algae and detritus removal in planted aquariums. These transparent, graceful creatures are known for their constant scavenging behavior, tirelessly cleaning surfaces, and consuming uneaten food. Amano Shrimp are highly effective in managing hair algae, green spot algae, and even some types of cyanobacteria.

In order to thrive, Amano Shrimp require a well-established aquarium with stable water parameters. They can coexist peacefully with other peaceful fish and invertebrates. Their cleaning habits and intriguing behaviors make them a captivating addition to any aquarium, and their contribution to maintaining a clean environment cannot be overstated.


When it comes to keeping your aquarium clean and balanced, these three fish species—Siamese Algae Eaters, Otocinclus Catfish, and Amano Shrimp—are remarkable allies. However, it’s essential to remember that while these fish can greatly assist in algae control and waste management, they should be considered part of an overall maintenance strategy that includes proper feeding, water changes, and regular monitoring.
