They may not be settled yet. This is a very skittish and shy fish, as it notes in our profile:

Lots of plants, and a good cover of floating, are the best ways to provide the "comfort" they need, and you seem to be heading in the correct way with this. Provided they have no boisterous or active-swimming tankmates, they should settle in. And not much water movement (filter current).
To deal with such fish and eating, frozen bloodworms and frozen daphnia work. Thaw some of either, and use a baster or similar to squirt a few toward the fish. They will likely gobble them up. You have to be careful not to get too close, as that will frighten them more.;-) This is an ambush predator.
