So my experience was first few days they weren't foraging at all just cuddled up under a cave I made and just stayed there probably due to new surroundings and water parameters. My tank is somewhat heavily planted so that might have aided them in feeling more comfortable. I have java moss, java fern, dwarf hairgrass, subwassertang, pogostemon octopus, some small crypts, bacopa, anubias petite so maybe all that helped.
Currently I've been feeding all inhabitant of the tank a variety of flake, frozen blood worms, brine shrimp, daphnia, repashy soilent green, north fin fry starter. I think they like the frozen stuff the best so far.
BTW water temp is about 75 deg F, zero ammonia and nitrites, 10ppm nitrates.
