For most loach species, including all the pangio species, all the hillstream algae eating species, and all to botiine loaches, it is best to have at least 5 if you have room in your tank. So if you have Yoyos or Polka Dots or Zebras or Blueberries or Kuhlis or Clowns or Sidthimunkis or Queens or Tigers or Skunks, and you have the space for them, get at least 4 more. If you don't have the space to house them comfortably at full size, stick with one, and if you have one of the nemachelius or schistura loaches do some research on the species first, as some of them are very territorial.
Weather Loaches also prefer to be in a group of five or more, but I find that my three are doing well together.
