How Do Siamese Algae Eaters Help?

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 constantly approach and explore the substrate, new plants, decorations, and even 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 on 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, they are often 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 highly active and energetic. If you have more than one, you will be happy to see them swimming around in a group and feeding in the same place until no algae are left in your tank. Some Siamese might be aggressive with other fish, thus observing them for a few days to ensure they don’t hurt other creatures in the tank. It might be a good idea to keep them away from minor or very calm fish, as they can be disturbed by this active species.

Although this fish will eat algae, mainly 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 food. This means feeding them less often; otherwise, they will no longer be interested in eating plants. A good way would be to limit the amount of food in a part of the tank that the Siamese does not frequent often.

Water Parameters for Siamese Algae Eater

Water Temperature

The recommended temperature for this fish is around 75-79° Fahrenheit, but they will survive if 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 fish; they have a lifespan of almost ten years. Also, once they form a couple, they will establish their territory and react aggressively 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 prominent place to swim, and a lot of algae to eat. A vital fact is that this fish can jump out of the tank at any opportunity. It means you should cover your tank with a lid. And also, make sure to have lighting your fish cannot touch and get burned.

When you put them 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 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.

You would roughly need a tank of 20 gallons to 30 gallons, which will give them a pretty large area to move about and explore. 

pH Level

Again, you need to satisfy specific parameters such as the pH level, hardness, etc.! You need to have a pH of 6.5 to 7.0, replicating specific acidic water conditions. And water hardness should range between 5 to 20 dH.

However, if you are new to this hobby, there are some factors that you should keep in check before you decide to add this fish to your tank! These fishes love to move around, as they lack a swim bladder. Also, these fish need some hiding spots right at the bottom of the aquarium, where they can enjoy being alone and rest!

To keep this fish healthy, you need to replicate its actual habitat. You can provide some cave holes and plains or even driftwoods as these spots give them the place to rest and hide from other notorious fishes in the tank!
