Do brine shrimp eggs have a shelf life? Just asking because I acquired a bottle of eggs marked 1966. Is it worth going to the store to get the salt to hatch them or have they gone bad by now?
I don't know the answer to your question, but what is that dog on your avatar? Is it painted?
I have read that marine salt mix produces a better hatch rate, but unless you have a SW tank it's hardly worth the cost. I'd try some w/table salt just to see if any are still viable; those eggs are almost as old as I am.
