General Description
Esomus caudiocellatus, a member of the Cyprinidae family under the order Cypriniformes, is among a dozen described Esomus species. These fish, often overlooked in the ornamental trade, are recognized by their enlarged pectoral fins and distinctive barbels. Particularly, Esomus caudiocellatus is identifiable by its lack of a dark lateral stripe and a dark marking on the caudal peduncle.
Aquarium Setup
For Esomus caudiocellatus, a minimum tank size of 160 litres is recommended. The setup should mimic their natural habitat, utilizing plants, driftwood, and rocks to provide hiding spots. These fish prefer well-oxygenated water with a moderate flow, optimal temperature between 22-28°C, and slightly acidic to neutral pH levels (see table).
Behaviour
Esomus caudiocellatus are known to be relatively peaceful fish, tending to school in groups. They may exhibit shoaling behavior and are generally active throughout the day. However, some aquarium hobbyists have noted instances of a wasting disease affecting these species, leading to a rapid decline in body mass and eventual death.
Feeding and Diet
In their natural habitat, Esomus caudiocellatus are omnivores, feeding on small invertebrates, algae, and plant matter. In an aquarium setting, they can be fed a varied diet including high-quality flakes, pellets, small live or frozen foods like bloodworms and brine shrimp, to ensure proper nutrition.
Reproduction & Dimorphism
Details specific to the reproduction and dimorphism of Esomus caudiocellatus are not provided in available information.
Habitat and Distribution
The distribution of Esomus caudiocellatus is not entirely clear; while specimens have been collected from the Salween river system in eastern Myanmar and northwestern Thailand, their presence in other locations is also possible. The etymology of the name "Esomus" is derived from Latin and Ancient Greek, referencing the fish's distinct long maxillary barbels, while "caudiocellatus" highlights the species' characteristic dark tail marking.
