I don't see how either of those fish could physically break eggcrate. At all. Unless what you are using is not the egg crate I own... As what I call eggcrate I struggled to cut with side cutters capable of slicing a finger off. No way a fish would break the egg crate I know of.

As for the thread user ... Do you have any spaces that perhaps are cut around wires or pipes or something like that? Maybe they found a crack.

I forego eggcrate now and use a canopy about 8" tall. I have not lost a jumper since. Not even a wrasse in several years. Short of loss while doing maintenance. I failed to notice a jumper during extended maintenance. Oops.
