Diamonds are tricky. I had one for over a year (no eggcrate) and never had a problem. Had to get rid of him due to a move. Started tank up again about 4 years later and I'm on my third Diamond Goby. The first two jumped (no eggcrate). The third is currenlty cleaning away (purchased eggrate). I've heard of people wrapping eggcrate in some sort of screen. Anyway, sorry to hear about your goby.
