Sorry for reviving a thread that's a couple years old, BUT I just saw my cherry shrimp rip through a couple corydoras eggs in my 10g tank. Pulled out a fry that was not ready to hatch yet. Kind of sad to watch, but it happens.
I should've taken a video, but I was too intrigued/mortified/whatever to think of it at the time. NEXT TIME I see cory eggs, I'm going to keep my phone at the ready.
Can't wait to get a breeder box...my cories have been laying eggs regularly.
