I'm not angry. I'm giving my opinion based on how the situation was presented and what I know about raising fry from my own experiences.
The fact of the matter is.. young fry must be fed daily, preferably multiple times a day, every. single. day. or they will die... period.. no ifs, ands, or buts about it.
The OP stated in the first post that he or she did not have fry foods prepared. In another post it was mentioned that they have brine shrimp. That's fine but brine shrimp require someone to hatch and feed them and water changes are a must because the shrimp will foul the water very quickly.
Unless they already knew someone who was familiar enough with fish to know how to do water changes and hatch brine shrimp it would have been more humane to destroy the eggs before they hatched.
Its a moot point now though because most likely the fry have hatched by now and are almost to free swimming where they'll be searching for food.
