Crossocheilus Cobitis

Datasheet

General Description

Crossocheilus Cobitis, commonly known as Siamese Algae Eater, is a member of the Cyprinidae family characterized by possessing 8 branched dorsal fin rays, two pairs of barbels, and a continuous midlateral stripe from snout to the caudal-fin base. This species, often misidentified in the aquarium trade, showcases distinctive features such as a narrow mouth and lacks a dorsal spine. The upper and lower lips are not connected, with the upper lip attached to the lower jaw by a thin membrane.

Aquarium Setup

When setting up an aquarium for Crossocheilus Cobitis, a minimum tank size of 90 litres is recommended. The habitat should include a rocky structure to encourage the formation of biofilm for browsing. The fish are known to ascend into midwater for feeding. Providing a variety of high-quality dried foods with added Spirulina or fresh vegetable matter such as shelled peas, blanched courgette, and spinach is essential for their nutrition.

Behaviour

In their natural habitat, C. Cobitis are aufwuchs grazers, feeding on algae, diatoms, phytoplankton, and associated microorganisms. In an aquarium setting, they exhibit browsing behavior and often graze on the biofilm that forms on rockwork. These fish require a peaceful environment and can be a beneficial addition to a community tank where they help control algae growth.

Feeding and Diet

Avoiding high-protein foods is crucial for Siamese Algae Eaters as they may not efficiently metabolize certain components leading to fat deposits and organ degeneration. A balanced diet of dried foods with added Spirulina and fresh vegetables like peas and spinach is recommended. They are known to feed on algae and other plant matter in their natural habitat.

Reproduction & Dimorphism

Information about the specific reproduction and dimorphism characteristics of C. Cobitis in an aquarium setting is limited. However, in their natural environment, these fish likely exhibit typical cyprinid breeding behaviors such as scattering their eggs. Dimorphism in this species may involve subtle differences in body size or coloration between males and females.

Habitat and Distribution

Siamese Algae Eaters are primarily found in the lower reaches of rivers with muddy substrates in regions ranging from Laos, Vietnam, and Thailand down to the Greater Sunda Islands of Sumatra, Borneo, and Java. They inhabit turbid waters and are often collected near submerged solid structures like logs and stationary boats. The species' type locality is recorded as Padang, Sumatra, Indonesia, and Jakarta, Java, Indonesia.
