I have kept Tesselated Darters, and had no problem getting them on Hikari Micro-pellets. The trick was getting them down in the water column so the darters could get at them, but eventually I had a couple that would come up to the surface to feed.
I think the trick to darters is very, very, very well aerated and clean water. At least it was for the Tesselateds I had.
