Yeah, Oceangirl, if you are cracking the egg raw, you would have to do something to clean the leftover white from the shell before you used it in your shrimp tank. But I do like CharleeFoxtrot said and boil the egg first, then after I peel the boiled egg, I just check to make sure there is no white stuck to the membrane before I drop some of the shell in the tank.
The only difference is I'm too busy with my shrimp to make egg salad so I just eat the boiled egg . . . Okay, the truth is I'm too lazy to make egg salad and it's just easier to eat it boiled!
And I like the art work, Oceangirl, nicely done!
