1 Live Kuhli Loach (also spelled Coolie Loach) - 3"+ long! by InvertObsession
If you are as fascinated by eels as we are, but are limited on space in your aquarium, than this is the fish for you!  This beautiful loach could easily be mistaken for an eel due to the translucence of its fins, yet it will never grow too large for a home aquarium.  They come from tropical climates, including Indonesia, Malaysia, Java and surrounding areas.  The Kuhli Loach is a truly elegant swimmer, its movement resembling a snake's slithering dance.  These fish have gorgeous coloration - they are mostly a deep burgundy with bright gold bands encircling the body.While the Kuhli Loach is rather adaptable to most tank conditions, it thrives in water that is medium-soft to medium with a pH around 6.0 to 7.0.  The ideal water temperature is around 75 - 85 degrees.These are nocturnal creatures and they like to hide when the lights are on, so plant or rock cover is important.  They also prefer sand substrate, as it's easy for them to burrow in it.  They are scavengers and will eat food and waste that sinks to the bottom of the aquarium.
