Dither fish?

[Luggy978]

Hi. I currently have a ebjd in my 29g tank on his own. I believe he had an eye problem as I have had to teach him to take sinking pellets in a certain spot in the tank. He does try to get other food but when he strikes for it he misses! I was wondering if it would be possible to put in some dither fish to help him to take flake from the surface. And if so, what fish would be compatible?

Thanks
