The Dwarf Chain Loach (Ambastaia sidthimunki) is a nano-sized member of the loach/botia family indigenous to Thailand. While its limited wild populations are in decline and nationally protected, this fish has fairly recently been farmed on a commercial level in the United States. In addition to its very attractive appearance, this beautiful loach is also highly desired due to its extremely active and outgoing personality as well as its relative adaptability. This is a fairly rare species and it is one of the few traditionally-shaped loach/botia species that can be considered a “nano” fish that is appropriate for heavily-planted aquariums.
