How to look after eggs?

Question

i have danio eggs which have been laid since 24 hours now and is also in a separate tank. i have an air stone and i was wondering should i put that in the tank for the eggs? or should i wait until they have hatched?

Answer 1

Wait until they have hatched.

Answer 2

put the airtone in the tank now itself. it will keep the water well oxygenated. the eggs won't be disturbed. remove the air stone after hatching as the fry will have problem swimming in the current!!!!!
