What is a Siamese Algae-Eater?
Origins and Scientific Classification
The Siamese Algae-Eater, also known as the True Siamese Algae-Eater, is a fish from freshwater. It is classified as Crossocheilus oblongus (formerly Crossocheilus siamensis). It comes from Southeast Asia, mainly in Thailand, Malaysia, Cambodia, Laos, and parts of Indonesia. This fish was first described in 1823 and is the main type of the Crossocheilus genus.

SIAMESE ALGAE-EATER Aquarium Setup Requirements
Tank Size and Water Parameters
Siamese Algae-Eaters need a big aquarium to move around. A tank of at least 55 gallons is best for one fish. They like water that’s well-oxygenated and has a moderate to high flow, just like their home rivers.
The perfect water has a pH of 6.0-8.0, temperatures between 68-80°F, and TDS of 50-250 ppm. Keeping the water clean with regular water changes is key to their health.
Decorations and Plants
Make the aquarium feel like their natural home with a sandy bottom, river rocks, and live plants like Java fern and Anubias. Adding driftwood and other decorations gives them places to hide and eat. A strong current is important, so use a high-flow filter or a small powerhead.
“A single Siamese algae eater can thrive in a 50- to 55-gallon freshwater aquarium, and they can tolerate water temperatures ranging from 68–80°F (20–27°C) and a pH level of 6.0–8.0.”
Keeping Siamese Algae-Eaters in Groups
Siamese Algae-Eaters do well alone, but they feel safer and less aggressive in small groups. Keeping 3-5 of them together helps prevent fights and lets them act naturally.
Adding plants and decorations helps reduce fighting within the group. These fish can grow up to 6 inches long. They need a big tank, at least 50-55 gallons, to live peacefully.
It’s important to have a large enough tank for a group of Siamese Algae-Eaters. They can be a bit aggressive with each other. A bigger tank with hiding spots can help them live together better.
| Fish Species | Maximum Length | Recommended Minimum Tank Size |
|---|---|---|
| Siamese Algae-Eater | 6 inches (15 cm) | 50-55 gallons |
| Chinese Algae Eater | 11 inches (28 cm) | 75-100 gallons |
| Flying Fox | 6 inches (15 cm) | 50-55 gallons |
Keeping Siamese Algae-Eaters in groups and giving them a good home makes them great at cleaning your tank.
Suitable Tankmates for Siamese Algae-Eaters
Choosing the right siamese algae-eater tankmates is key for a peaceful aquarium. These fish are calm and can live with many community fish. Just make sure they have enough food and aren’t too shy.
Ideal Fish Companions
Great friends for Siamese algae-eaters include barbs, danios, and some south american cichlids. Livebearers like guppies and mollies also work well. Pick fish that are about the same size and like to swim as much as the Siamese algae-eater.
Compatible Invertebrates
Siamese algae-eaters get along with big shrimp like amano shrimp and dwarf crayfish. But, don’t mix them with tiny shrimp because they might eat them. Atyopsis fan shrimp are a great choice because they like strong currents too.
| Tankmate Type | Compatibility | Examples |
|---|---|---|
| Fish | Suitable | Barbs, danios, certain south american cichlids, livebearers |
| Invertebrates | Suitable | Amano shrimp, dwarf crayfish, atyopsis fan shrimp |
| Smaller Shrimp | Not Suitable | Neocaridina shrimp |
Feeding Siamese Algae-Eaters
Siamese Algae-Eaters eat both plants and animals. In the wild, they look for algae, dirt, and small bugs on the river floor. In aquariums, they like to eat algae wafers, spirulina flakes or pellets, and blanched veggies.
Supplementing Their Algae Diet
It’s key to add plant-based foods to their diet to keep them eating algae. They might choose protein-rich fish foods over algae if given the chance. A diet with both algae and extra food helps them stay healthy and good at controlling algae in the tank.
- Siamese Algae-Eaters typically grow up to 6 inches (15 cm) in length.
- Juvenile Siamese Algae-Eaters need lots of nutrients to grow and will look for algae and small food bits.
- As they get older, Siamese Algae-Eaters might not want to eat as much algae, so extra food is important.
By giving them a mix of algae foods and extra food, your Siamese Algae-Eaters will stay healthy and active. They’re important for keeping your tank clean by eating hard-to-control algae. They’re a great choice for any planted or community tank.
Breeding Siamese Algae-Eaters in Home Aquariums
Breeding Siamese algae-eaters at home is rare. Some have bred them, but it’s not common. The exact steps to breed them are not well-known to most people. Most of these fish come from the wild, not fish farms, because breeding them in captivity is hard.
Trying to breed Siamese algae-eaters at home is tough. You need to change the water, flow, and light to help them breed. Keeping the water right, with a pH of 6.5 to 6.8 and a temperature of 77°F, is key. Also, having well-oxygenated water and more algae-eaters might help them spawn.
Knowing the gender of these fish can help with breeding. Females are wider than males when viewed from above. This can help pick the right fish for breeding.
“Breeding Siamese algae-eaters in captivity is not a well-documented process, and the specific requirements for successful spawning are not widely known among aquarium hobbyists.”
Trying to breed Siamese algae-eaters at home is exciting but rare. Aquarium fans who want to try need to play with different water settings and conditions to encourage breeding. But, even with the best conditions, breeding them is still hard and not very successful compared to other fish.
Sourcing and Identifying Siamese Algae-Eaters
Siamese Algae-Eaters, or Crossocheilus oblongus, are popular freshwater fish known for eating algae. But, finding the real Siamese Algae-Eater can be hard. They often get mixed up with fish like the Chinese Algae Eater or the Flying Fox.
It’s best to buy Siamese Algae-Eaters from trusted online stores or your local fish shop. They usually cost about $10.00 AUD each. But, prices can change depending on where you are and how easy they are to find.
It’s important to know how to tell a Siamese Algae-Eater apart from others. They can grow up to 6 inches (16 cm) long, which is bigger than some similar fish. They also have a long body and a flat head, unlike the Chinese Algae Eater.
Make sure you’re getting the Siamese Algae-Eater you want by checking the fish closely. If you don’t, you might end up with a different fish that doesn’t eat algae as well.
“Proper identification is key when purchasing Siamese Algae-Eaters to avoid getting a closely related but distinct species.”
By choosing trusted sellers and checking the fish’s identity, you can be sure you’re getting these helpful algae-eaters for your tank.
Dispelling Myths About Siamese Algae-Eaters
Siamese Algae-Eaters are often seen as a magic solution for aquarium algae. But, they’re not a full replacement for aquarium maintenance. They can’t keep a tank perfectly clean on their own. In fact, they might spread algae spores through their waste.
Also, one Siamese Algae-Eater won’t be enough for big algae problems. You might need a group to see results, which can increase the tank’s bio-load. It’s key to know their limits and not rely too much on them for siamese algae-eater myths.
| Myth | Reality |
