Overview
The Siamese Algae Eater is built like a racer and is prized as the best algae eater for planted aquariums. It is distinguished from other Crossocheilus species in having a black longitudinal stripe on its sides. Unlike the similar-looking Flying Fox (Epalzeorhynchos kalopterus), the fins of this species are transparent, and it has only a single pair of barbels on the upper lip. The mouth has thick lips with many folds that form a sucking disc to rasp algae off a variety of surfaces.

Feeding
Crossocheilus siamensis feeds on plankton and algae in the wild, and its diet in the aquarium must also include vegetable matter. Provide a variety of Spirulina-based foods, including flakes and wafers, as well as occasional treats of live foods like bloodworms and brine shrimp. Unlike most other algae-eating species, it will eat red and black algae, but will not harm plants.
Aquarium Compatibility
The Siamese Algae Eater is a peaceful, active species best kept in groups of at least three. It can be somewhat “testy” with its own kind.
Breeding/Propagation
No reports of breeding in the aquarium.
Notes
Like the Flying Fox, this species also exhibits a peculiar resting position: it keeps its body “propped up” with its tail, pelvic and pectoral fins.
