Dwarf Loach

The Dwarf Loach (Yasuhikotakia sidthimunki) also known as the Ladderback Loach, Pygmy Loach, Chain Loach or Chain Botia, is a freshwater species of fish commonly found in the pet trade. Its natural habitat is the
Mae Klong River and the Khwae Noi River in western Thailand. It is an endangered species and is protected in Thailand. It was thought to be extinct until recently rediscovered in Sangkhla Buri.

The Dwarf Loach can grow up to 2 inches in length. It closely resembles the Black-lined Loach (Yasuhikotakia nigrolineata). The differences are easily seen when the fish are still young. Juveniles of the Dwarf Loach have dotted patterns while the other has horizontal lines. The chain pattern seen in Dwarf Loaches begins when they are still young as well.

The binomial name of this fish is in honor of Aree Sidthimunk, a researcher at Department of Fisheries, Ministry of Agriculture.
