Acanthophthalmus kuhli (Kuhli Loach, Акантофтальмус кюля)

Coolie Loach, Giant Coolie Loach, Leopard Loach, Cinnamon Loach, Колючеглаз. This loach is a peaceful community fish and a great scavenger of uneaten foods that settle to the bottom of the aquarium. They hide during the day, but are quite lively and active in the evening. Though they do not school, they will be more likely to come out of hiding if they are kept with some companions. A singly kept Kuhli Loach will seldom be seen. They are found in southeast Asia; Sumatra, Singapore, western Malaysia, Java, Borneo, and Thailand. The most important thing for these loaches is that they always have clean and well-oxygenated water. Frequent water changes of about 30% a week are needed for the Kuhli Loach. Loaches are more susceptible to disease than other aquarium fishes. Cold water and condition changes can also cause stress to this fish which makes them even more prone to disease.
