Breeding CPD's with crayfish

[Antler]

I'd like to breed some CPD's in a 20 long. It has fake plants and river rock, stocked with a blue Florida crayfish and a rainbow shark. Would the shark or crayfish eat the fry? Would any make in too adult?

CPDs are extremely shy fish and would be out competed for food and likely be eaten with a cray and RBS. Adults included.
