All my Front's have eatten pellets, NLS is prefurred. They will even eat pleco waifers when they are big. I also gave them a treat of blood worms or frozen krill. As for the set up lots of big caves they like to hide i usually, keep mine with other fish they can't eat larger barbs and clown loaches, the tend to come out and swim around more. I have just sold a Breeding group of F1 mpimbwe blue's 13 in total, very nice fish.
