Siamese Algae Eater

In many tanks, algae are the biggest problem. No matter how much you try to control the algae, they keep appearing and bothering your tank. They appear on the substrate, on your new plants, on the decorations, and even on the wall of your tank. Even more so, sometimes you cannot even maintain good lighting in your tank because algae will fill it.

Get rid of Algae

To get rid of algae without all the chemicals and without cleaning your tank daily, you can get an algae eater like the Siamese fish. This fish will feed from algae and keep your tank clean and clear.

The Siamese Algae eater is a freshwater fish found in every pet store. Although they have unique features, very often they are confused with other fish so pay great attention when buying one.

The Siamese fish is considered one of the best algae eaters, as it is extremely active and energetic. If you have more than one, you will be happy to see them swimming around in a group and feeding from the same place until there is no algae left in your tank. Some Siamese might be aggressive with other fish, thus observe them for a few days to make sure they don’t hurt other creatures in the tank. It might be a good idea to keep them away from small or very calm fish, as they can be disturbed by this active species.

Although this fish will eat algae, especially red algae, it will not miss the chance to “steal” the food of other fish. The older they are, the more they will eat other kinds of food. This means feeding them less often, otherwise they will not be interested to eat plants anymore. A good way would be to limit the amount of food in a part of the tank where the Siamese does not frequent often.


The recommended temperature for this fish is around 72-75° Fahrenheit, but they will survive if there are only a few degrees difference. On the other hand, some aquarists claim warmer water will cause it to eat less and increase the algae, so it is better to keep them in tanks with cooler water.

As small and cute as this fish might seem, they will live longer than most of the fish; they have a lifespan of almost ten years. Also, once a couple is created, they will establish their territory and react aggressive towards anyone who tries to come around them.

In general, most aquarists choose to keep this fish in heavily planted tanks where they will have plenty of places to hide, a large place to swim, and a lot of algae to eat. A vital element is the fact that this fish will jump out of the tank with any opportunity. This means having a permanent cover on your tank and make sure to have lighting the fish cannot touch and get burned.

When you putt hem in the tank for the first time, you will be surprised to see they start eating algae right away. They rarely need accommodations and can live in any tank, no matter the size. However, consider putting them in a large tank after a few months, because they grow up to more than 5-7 inches. The older they get, the more they refuse to eat algae, and so you will have to bring a few young ones in to keep your tank clean.


Since you have the perfect cleaners in your tank, you can eliminate chemical substances and any other tricks. Also you can increase your lighting without algae conquering the substrate. It is recommended to keep the water parameters balanced all the time; although they are pretty resistant, they do not live well in hard water and their lifespan will be reduced dramatically.

Make sure they have the minimum conditions and you will be able to enjoy a clean, beautiful tank that is algae-free and populated with active fish.
