Scuds and Redcherry shrimp + Fish Eggs

[Potaqua]

I know from a lot of breeders that said that scuds and red cherry shrimp eat fish eggs?

I have never ever seen them eat them. I have seen them clean them and toss them aside after they clean them.
Is that weird behavior for them?

In my experience they are not egg eaters but cleaners as you experienced.  The issue I notice that I believe is why they get the egg eater label is the damage caused to the eggs and the new hatched wigglers. 
 

I have also seen them clean and discard eggs.  I’ve also seen fertile eggs then deteriorating after cleaning and no longer being viable.  
What I noticed when I hatched African dwarf frogs is them cleaning the brand new hatched and inflicting enough damage they perished.

Should I be worried? For example, My white cloud minnows always seem to co-exist and breed with the scud in their tank.

If it’s working I would leave it be.
