General Description
Nemacheilus anguilla, also known as the Indian loach, is a peaceful freshwater fish belonging to the family Nemacheilidae. It can be distinguished by its dark flank markings and almost complete lateral line extending to the anal fin. These fish have elongated bodies, large eyes, and a small, arched mouth.
Aquarium Setup
Setting up an aquarium for Nemacheilus anguilla involves replicating its natural habitat of flowing streams. A tank of at least 60 liters should be designed with a substrate of rocks, sand, gravel, and boulders. Driftwood branches can be added for shelter and decor, with hardy aquatic plants like Microsorum and Anubias attached. Maintaining high oxygen levels and water movement is essential, achieved through power filters, powerheads, or airstones. Regular water changes of 30-50% are recommended to keep the tank clean.
Behaviour
This species thrives in the company of peaceful tank mates, particularly cyprinids and loaches that inhabit similar biotopes. N. anguilla is peaceful with conspecifics and enjoys being kept in groups. Even though it can coexist in larger tanks with territorial species, it is best kept in a group of four or more for confidence.
Feeding and Diet
Nemacheilus anguilla is an omnivorous fish with a diet consisting mainly of small insects, worms, crustaceans, and zooplankton. In an aquarium, they readily accept dried foods but should be supplemented with live or frozen options like Daphnia and bloodworm for optimal coloration and condition.
Reproduction & Dimorphism
Reproduction of N. anguilla has been observed in captivity, with males displaying a bright red snout and darkened body patterns during spawning. Females possess a rounder abdomen and paler coloration. Courtship involves male-led behaviors, and eggs are released midwater, near the filter outlet. Fry can be raised separately to increase survival rates.
Habitat and Distribution
The Indian loach is endemic to the Western Ghats mountains in southwestern India, specifically found in rivers and streams with gravel and boulder substrates. Polluted habitats and the introduction of exotic species pose threats to their natural environment. N. anguilla has been recorded in various river drainages across Maharashtra, Karnataka, and Kerala.
