Mastacembelus dayi
The Black Spotted Eel may not be brightly colored but it has a beautiful design!
The Black Spotted Eel is also known as the Polka Dot Eel or Spotted Spiny Eel. As you can see in the photo above it sports an exotic looking color pattern. Smaller specimens have fewer but larger spots. This elegant patterning makes it a beautiful fish, one that is well worth having in your aquarium.
The Black Spotted Eel has been imported for a long time, and over the past few years many thousands have been shipped from Thailand. Mastacembelus dayi is considered to be very rare by science, but fortunately this is probably not true. Supposedly only 3 specimens have ever been found and these 3 were used to describe the species. This is probably just a case of local fisherman knowing more about the distribution of a fish than the scientists do.
As with most members of the spiny eel family, the attractiveness of this eel lies in its unusual color pattern and interesting behavior. Although not considered to be true eels, the body shapes of all members of the spiny eel family, Mastacembelidae, are definitely eel-like.
