The Kuhlii Loach (Pangio semicincta)

The wormlike Kuhlii Loach is a fascinating creature for those who like their fishes to be a little weird. This species crawls, wriggles and writhes its way through life, seldom leaving the bottom of an aquarium and oftentimes found lurking just beneath the surface of the substrate. But, with food in the tank or the lights turned off, this energetic species will soon begin to bounce about spastically, making for an entertaining show.

It can be found commonly in the stagnant waters of peninsular Malaysia, Sumatra and Borneo, in habitats with muddy or sandy bottoms. For this reason, sand makes for an ideal aquarium substrate, allowing this secretive fish to bury itself with ease. Another important consideration is the tendency of this inquisitive species to explore every nook and cranny of its surroundings, often resulting with it wedging itself into aquarium filtration. So be sure to prevent this with some mesh or foam on any intake large enough to be squirmed into.

With a maximum size of just a few inches, a Kuhlii Loach can be added to even the smallest of aquariums. Feeding is easily accomplished with sinking carnivore pellets and frozen foods. The species naturally occurs in groups and no doubt appreciates some company in captivity. It is also unusually peaceful and is easily kept with even some of the more timid species, such as smaller danios and rasboras. Though perhaps not everyone’s cup of tea, the Kuhlii Loach can definitely make for a great oddball that is sure to delight many.
