Not sure why when people see a Tire track spiny eel with faded patterns they assumed they are the same species with the commonly seen tire track spiny eel with lots of patterns. The one with the faded patterns is scientifically called Mastacembelus armatus. The other with lots of patterns is called Mastacembelus favus. They are both different species under the name of Tire track spiny eel. There are more than 4 species under the name of tire track spiny eels.
