The Siamese algae eater exhibits a distinctive black horizontal stripe that spans from its nose to its tail.

The phenomenon of the stripe rapidly fading to facilitate concealment in response to battles or stress has been noticed in the fish.

The occurrence of authentic Crossocheilus siamensis specimens, characterized by the absence of maxillary barbels and a prominently fringed V-shaped upper lip, is infrequent within the commercial aquarium industry.

Siamese algae-eaters have the potential to reach a maximum length of 15 centimetres (6 inches) during a span of two years and can exhibit a lifespan exceeding 10 years under ideal environmental circumstances.

The fish species under consideration is highly esteemed within the aquarium trade due to its unique ability to consume red algae, especially the varieties commonly referred to as ‘black brush’ or ‘beard’ algae.

The red algae-eater, scientifically known as Crossocheilus langei, is closely associated with the topic at hand. This particular species is commonly available in the market under the name Siamese algae-eater.

The organism possesses a prominently coloured, elongated body with a distinct brown hue and a subtly flattened ventral region.

The animal exhibits a conspicuous brown-black horizontal stripe that spans from its nose to its tail. The maximum recorded length of this particular fish species is approximately 16 centimetres (6.3 inches).

The organism exhibits little maxillary barbels and a shallowly arcuate upper lip lacking fringes. There are two other species that are commonly marketed under the term “Siamese algae-eaters.”

These species include Crossocheilus atrilimes, which has a preference for Java moss over red algae, and an undescribed species of Crossocheilus.

How Do I Describe the Appearance of the Siamese Algae Eater?

Authentic Siamese algae eaters possess a slender physique, characterized by a lengthy and thin body structure that can extend up to a maximum length of six inches.

The typical colouration of this species is commonly observed as a pale grey or gold hue, accompanied by a distinctive black stripe that extends longitudinally from the cranial region to the caudal extremity.

The fading of stripes in certain organisms may occur in several contexts, such as during mating displays, periods of stress, or as a potential mechanism for concealment, although the latter is less frequently observed in aquarium settings.

There are no discernible distinctions between men and females until approximately 3-4 years of age, at which point the sole distinguishing characteristic is their physical size.

Females exhibit a mass that is around 30% greater than that of males.


How Do I Describe the Behaviour of the Siamese Algae Eater?

The majority of their temporal allocation is dedicated to occupying the lower strata of the tank.

In this context, the organisms engage in locomotion within their aquatic environment until they locate a specific area characterized by an abundance of algae.

Subsequently, they are inclined to remain stationary in this location until the algae is depleted.

When individuals are kept in close proximity, they tend to aggregate and exhibit group behaviour, leading to the observation of collective feeding activities inside a shared spatial location.

While they exhibit infrequent aggression, these organisms display high levels of energy and engage in rapid swimming behaviour.

This implies that they should refrain from engaging in aggressive behaviour towards other fish, however, they may potentially disrupt and agitate more peaceful species.

In the event of violent behaviour, it is advisable to constantly monitor the individuals involved over a span of several days. Should the issue persist, it may be necessary to consider separating them.


How Do I Describe the Diet of the Siamese Algae Eater?

The primary component of their dietary intake is reflected in their nomenclature. In their natural habitat, these organisms consume algae, plant matter, and vegetation; nevertheless, it is important to note that they do not exclusively adhere to a herbivorous diet.

Scavengers exhibit a dietary behaviour characterized by consuming a wide range of food sources, such as deceased aquatic organisms and various insects, as they forage for sustenance.

Providing sustenance for these organisms within the confines of an aquarium is a straightforward task since they exhibit a non-discriminatory feeding behaviour and readily consume a wide array of substances introduced into the tank.

This encompasses commercially available flake and pellet feeds, algal wafers, as well as live foods.

Prominent instances of live food sources include brine shrimp and bloodworms, with frozen alternatives also proving to be effective.

Sinking food, such as pellets, is beneficial for bottom-dwelling fish due to its increased likelihood of descending beyond fish occupying higher positions within the tank.

Overfeeding may provide a concern due to the presence of preexisting algae and plants within the tank prior to the designated feeding period.

In certain instances, Siamese algae eaters may exhibit a preference for alternative food sources over algae consumption, particularly when excessive quantities of supplementary food are consistently provided.

How Do I Describe the Habitat of the Siamese Algae Eater?

Siamese algae eaters are commonly observed inhabiting the heavily vegetated rivers and streams of Southeast Asia in their natural habitat. The habitat preferences of closely related Asian Carp are identical.

The aquatic environment in these tropical seas exhibits a mild level of acidity and typically lacks a significant water flow.

Beneath the surface, a diverse array of flora, geological formations, and fallen timber can be observed, serving as habitats and sources of refuge.

The temporal allocation of an algae eater is divided between seeking refuge within these shelters and foraging for sustenance on various surfaces.

The primary constituents of the riverbed comprise predominantly algae, along with various other organic matter that undergo sedimentation.

The exploratory behaviour of this particular group of individuals is suboptimal, as they exhibit a tendency to confine their activities to familiar shelters and display limited inclination to travel towards the water’s surface.


How Do I Care For My Siamese Algae Eater’s Aquarium?

Crossocheilus langei, a robust species of red algae-eater, is frequently encountered in the commercial aquarium industry and is widely recognized as a highly sought-after and efficient organism for maintaining optimal cleanliness by consuming algae within tanks.

These aquatic organisms exhibit high levels of activity and agility in their swimming patterns, often engaging in collective behaviour known as schooling when maintained in a group.

However, it is important to note that certain individuals within the group may have aggressive tendencies towards their conspecifics or closely related species.

The red algae-eater is commonly suitable for inclusion in a variety of community tanks and is purportedly less prone to aggression compared to comparable species such as the Chinese algae-eater, red-tailed black shark, and rainbow shark.

The preferred water temperature range for this species is between 24 and 26 degrees Celsius (75 and 79 degrees Fahrenheit).

It thrives within a pH range of 6.5 to 8.0 and requires a water hardness level of 5 to 20 degrees of German hardness (dH).

Due to its efficacy in algae removal, the red algae-eater is commonly favored by aquarists for placement in thickly planted tanks with ample illumination, as a preventive measure against algae growth.

In contrast to other species of aquarium algae-eating fish, the red algae-eater fish is highly esteemed for its capacity to consume red algae, with a special emphasis on the Audouinella genus.

The fish, meanwhile, exhibits opportunistic feeding behaviour and demonstrates a preference for consuming pellets and many other types of sustenance, a proclivity that intensifies as the fish matures.

It is imperative to ensure that the lid of the tank is securely closed, without any significant openings that may facilitate the escape of the fish from the tank.

Due to their inability to remain suspended in mid-water, these organisms exhibit a preference for driftwood, rocks, and certain plants that possess the capacity to provide support for their resting.

Siamese algae-eaters exhibit a tendency to form schools, however, they are also capable of leading solitary lives.

When two individuals are housed in close proximity, it is common for them to develop their own distinct territorial boundaries when they reach maturity.

These fish have the potential for longevity, as evidenced by accounts of lifespans reaching up to a decade.
