Crossocheilus reidi

Crossocheilus reidi is one of several algae-eating cyprinids from Myanmar that closely resemble the true Siamese Algae Eater but represent distinct species. It shares the characteristic dark lateral stripe of the genus, though the stripe may terminate differently at the tail and the body proportions are subtly more robust. Like other Crossocheilus species it is a diligent grazer of soft algae and biofilm from plant leaves, glass, and hardscape.

In the aquarium C. reidi adapts readily to standard community conditions and is peaceful toward most tankmates. It is more frequently encountered as a bycatch in SAE shipments than as a deliberate import, making it a pleasant surprise when correctly identified. Its care and behaviour in captivity are effectively identical to those of C. oblongus and C. langei.

For planted tank keepers seeking reliable algae control, Crossocheilus reidi is a worthwhile occupant, particularly valued for its willingness to consume the types of filamentous algae that many other species ignore.

Water: Temperature 22–28°C, pH 6.5–7.5, GH 5–15; well-oxygenated water with moderate current preferred. Tank: Minimum 120 L; smooth rocks, driftwood, and open substrate for foraging; some natural algae growth beneficial. Feeding: Algae wafers, blanched vegetables, sinking pellets; grazes continuously on tank surfaces; supplement with frozen foods. Breeding: Not bred in home aquariums; commercial breeding uses hormone induction on fish farms in Southeast Asia. Compatibility: Peaceful with most community fish; one per tank unless very large; avoid housing with other Crossocheilus to reduce territorial interactions.
