Sorry to hear Gary.
I have a black lab and now own a Jack Russel as well. Both are really great (the Jack Russel thinks she is huge as well) and loving dogs.
The dead eggs aren't eggs of the tetra. They are eggscatterers and they don't stick on the glas. It might be a combination of an overfed eggbound female.
Think you can forget that. Our two only eat bloodworms as well and a sometimes a little bit of tubifex.
Ours lay for the glass to ask for food. To be honest they can't be hungry hahahah
