You have to feed them. So if they are only taking black worms that is what you have to give.
Gel foods are ideal for making your own food. They are relatively easy to prepare, you control the ingredients (which can include prepared foods). This can allow you to put in a high quality prepared food and blackworms.
Most LFSs are willing to make special orders. It should not be a problem to be willing to prepay for something and get it, most LFSs are not willing to refuse money. Most foods are easily available online as well.
As stated, getting them to associate an object with food helps a lot. They cna sense metal tongs in the water, so that can be used. They can also learn very quickly to associate bowls with food.
I plan on feeding New Life Spectrum. I know that in general rays will take it, I just have to get mine on them. (Whether it is just the ones at work or if I do end up getting rays at home.)
