Yes they usually need live food initially but will usually come around quickly. I do still recommend including live foods like ghost shrimp in their diet, not only for their nutrition, but as enrichment for a captive predator. The problem as that size is finding ghosties small enough, if you have access to amphipods that would be great. Amphipods are harder to come by for some reason, other pods would be worth a try to get them settled. Although copepods are too small, it will keep them from starving and give them a chance to acclimate. Yes, live black worms are very welcomed but I don't of an online source. I just grab a scoop with hemo's and they come right up to take them, initially you can just drop a clump in front of them. Initially turn the pumps off to calm the flow, eventually they will get more confident and chase things down. I do turn the pumps off when I feed black worms and other foods from a pipette, they come right up and take the food right from the pipette. You can also try feeder guppies, although getting them to a point where they can catch them can be challenging. In a tank that small I would drop a couple of appropriate sized guppies and/or ghosties in, and let them hunt. If overnight the prey is still there, I would use my herding method to help them out. Using a feeding stick to herd the prey into a point where they catch them. They do their best hunting at night so it is very likely they will catch them during the overnight hours.
Their nature would be not to eat the pom pom crab, they don't usually eat hard bodied inverts. Make sure you have them eating well before you try it. I say it's in their nature, but in captivity unnatural things may happen.
Many have used this thread to help them acclimating their little red rooster.
aka pygmy red rooster waspfish, red bandtail waspfish. I know I said I was finished with new additions, these had been on my list for a couple of years and this trio was at a lfs, so i picked them up. I have seen questions regarding these guys from time to time, and frustratingly no one ever...
