Shrimp in my sump?

[NeedAReef]

So, I put a pair of peps in my fuge section of the pump to float. I had several bags of things.... Well when I was opening all the stuff yeah my peps went in the sump accidentally ...
I have a standard three section sump. First is Skimmer chamber from the tank then overflow into fuge then overflow into return. There are baffles but no real way to stop things from going over the overflow into the next chamber. However no way to get the shrimp back into the fuge section and even if I do... They will do this again I assume.
So is there a way to maybe use egg crate and block off the overflow from big shrimp but let babies or pods go thru? If you have done it pics would be appreciated
Are they OK in the return chamber with the Heater and pump?

I probably wouldn't leave them in the return chamber or the sump (too many things to simply get sucked into).

That's what I am thinking just have no idea what to do to prevent them doing it again.
