Yup yup. I'm not especially planning to breed, just keep them, but their pickiness about food is why I'm planning to keep them only with some Hara Jerdoni, which has similar food needs. I've heard people have good results from Grindal and White worms, which are pretty easy to grow, as well as Daphnia, black worms, and blood worms. Msjinkzd, who's a really nice dealer of D. Dario, has had luck with some frozen foods as well.
Not impossible to feed, but definitely tricky!
"Less bad" does not equal "good".
