Quarantine Crayfish for Rays

[Damascus]

I have some crayfish that are currently breeding to excessive amounts in a native tank I keep.

I would like to feed them to my rays, but want to quarantine a breeding project so that I can safely feed them to other fish.

What is the best way to do this? I have been simply freezing them in flats and feeding them this way but I'm sure they would appreciate hunting down live ones.

Any advise would be appreciated!

Yo brother, I have a feeling u would get some suggestions if u posted this in the inverts section. I believe any meds that aren't copper based are what u want for crays, but no real help from me. Good luck homie.
