The fish will learn to eat from the turkey baster, and will soon be unafraid of it. Offer that explanation if discovered. If you see any of the comma ones turning dark, they are pupating, so feed them at once. This might sound like a hassle, or even dangerous, but it doesn't have to be if you're careful. After awhile, you may get the choclates to eat a good flake food if you squirt it past them with the baster.
Earthworms are a great food too.
Perhaps the smell will tempt them. Grindal worms are a dependable year round live food as well. Check the Krib for more on these.
