Can fish see NLS pellets on a black tank bottom?

[syrss]

This may be a strange question, but I am doing a bare bottom FOWLR, and there is a piece of black plastic underneath the tank (LeeMar Rimless). I am worried that if the dark colored pellets falls to the bottom and the fish will not be able to see it and not pick it up.

Anyone has experience with a similar setup (or black sand)? How did it work out? I know I can put a white cutting board in the tank but trying not have to.

TIA,
Ron
