Siamese Algae Eater - Crossocheilus oblongus : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Siamese Algae Eater (Crossocheilus oblongus) is a renowned freshwater fish species cherished for its adept ability to control algae growth within aquatic environments. This species has gained popularity among aquarium enthusiasts due to its distinctive appearance, peaceful nature, and valuable role in maintaining tank aesthetics and balance. These fish are suitable for both novice and experienced aquarists alike. With its dynamic behaviour, the Siamese Algae Eater stands as an engaging and practical addition to various aquatic setups, contributing to both the visual appeal and ecological harmony of the aquarium.
Siamese Algae Eaters are optimally maintained either as solitary individuals or in groups of 5 or more, fostering a cohesive social structure. Forming smaller groups may inadvertently lead to territorial disputes. Owing to their peaceful demeanour, they serve as excellent companions for a diverse range of species, including Barbs, Rasboras, Loaches, Rainbowfish, and certain larger Tetra variants.
It is judicious, however, to exercise caution when considering closely related or visually similar species, as well as fish like the Ruby or Red Tailed Black Shark. Furthermore, the dynamic and abrupt darting behaviour of Siamese Algae Eaters should be acknowledged, as it could cause distress among more timid or apprehensive aquatic inhabitants.
The tank configuration should ideally possess elongated dimensions, providing these energetic fish with ample swimming area. Employing a secure lid is imperative, as this species is known to exhibit jumping tendencies. Prudent attention should be directed towards establishing efficient filtration and achieving an adequate flow rate, emulating the clear, swift-flowing, and well-oxygenated stream habitats from which they originate.
Most aquatic plants can coexist harmoniously with Siamese Algae Eaters, thus encouraging a lushly planted environment along the tank perimeters. To evoke the ambience of a riverbed, the incorporation of a sandy substrate, bogwood, and smooth rocks is advised. Utilizing robust lighting serves a dual purpose: promoting algae growth while fostering healthy plant development.
One of the most distinctive features of the Siamese Algae Eater is its thick black stripe that runs from the nose to the tail. This stripe, which can fade during mating displays or times of stress, adds to the fish's striking appearance. The clear caudal fin and Rostral barbels give them an almost whimsical charm that can bring a unique element to any aquarium.

Natural Habitat
The Siamese Algae Eater is a fascinating fish that is native to Southeast Asia. This species can be found in the Chao Phraya and Mekong Basins, as well as the Malay Peninsula. In their natural habitat, they inhabit streams and rivers with dense plant life and slow currents. These waters are slightly acidic and provide a rich environment for the Siamese Algae Eater to thrive.
Rocks, plants, and logs provide ample hiding spots for these fish. While half of their time is spent hiding in these shelters, the other half is spent scouring the surfaces for food. Their diet consists mainly of algae, but they also consume other types of organic matter that sink to the bottom of the river. Despite their shy and reclusive nature, the Siamese Algae Eater is a fascinating fish to observe in the aquarium.
Breeding
Breeding Siamese Algae Eaters in home aquariums is a difficult task as successful breeding has only been achieved through the aid of hormones in farms. Moreover, determining their sex requires careful observation, making it challenging to breed them even if the water conditions are changed. Currently, there is limited knowledge on how to successfully breed them in home aquariums.
Diet & Feeding
The Siamese Algae Eater is an omnivorous fish that will consume various foods, including algae, plant matter, and vegetation. Specifically, they are efficient at consuming algae off live plant leaves. However, it is essential to provide a balanced diet to ensure optimal health and growth. A high-quality diet for the Siamese Algae Eater should comprise a variety of foods such as live, freeze-dried, or frozen bloodworm, brine shrimp, or tubifex, along with pelleted foods and algae wafers or vegetable-based foods. Incorporating such foods in their diet will help ensure they receive essential nutrients and maintain a healthy balance.
