i Was just wandering i do alot of salmon fishing and always trow away the eggs would by chance if i froze them in little cubes could i feed them to my oscars

No idea about the parameters of salmon eggs. I fed my oscars with frozen beef heart or pork spleen. They seems to be in good health until now & grows fast.

I see no problem feeding your oscars salmon eggs, but as with all foods dont make it 2 often, keep it as part of a varied diet
