I just bought a group of 6 wild caught petricolas today and they seem to be ready to breed. I have females ready to spawn with their fat belies. My question is does anyone know what size marbles to use for their cave? Please let me know.

Marbles come in one size so any marbles should do.

I think standard glass marbles are just over half an inch, 5/8" or something like that. (Metric that would be between 12-15mm).
I don't think the size is very critical, the point is that there should be small gaps between the marbles, and they should not be so big that the fish can get in there and eat the eggs, but big enough for the eggs to fall down the gaps quite easily.
