I wanted to say botia dario http://www.loaches.com/species-index/botia-dario but i think the head shape may be wrong. The color markings on the one you posted in the second set of picutres is nearly the exact same though.
On second thought, the second set of pics sure does look like a b. dario to me. Looks just like my three. They're great fun btw, LOVE to play, and snuggle with the plecos. I'm eager to round out my school so they'll be even happier.
They love shrimp pellets, and fight over algae wafers. Profile says they like veggies, but mine havent taken to them yet
