Not Zebra, Tiger or Polka D
It's actually a yoyo loach aka Botia almorhae. You can actually spell yoyoyo on the one you photographed & are better in groups of 5+. I have male/female pair in my tank.
Chain stores usually carry them. $5-8 each. Avoid the really small yoyo loaches & don't buy a skunk loach even if they're $2 or less.
Once yours gets comfortable, don't be surprised if you find a bunch of empty ramhorn snail shells. Pond snails stand no chance. Trumpet snails should survive a "loaching" if they're small.
Also, if you have amphipods in the substrate, or plants with bugs/worms nesting on the inside, loaches will uproot & rip apart the plants to get at them.
