If they are caring for the eggs chances are they will also care for fry, but the issue comes when they start swimming... the other fish in the tank will try to eat them. It would be in the pairs best interest, as well as their tank mates to get them a 20g tall tank for them, with a sponge filter and heater, as well as a piece of slate or upside down plant pot to spawn on, and a plant or 2 for security. No gravel or anything as it will trap fry, as well as waste and bacteria... pm me if you need more help.
