Hatching of cichlid eggs

[STAR]

Hi,

I have a pair of cichlid which already laid eggs but somehow haven't hatch after 4 days. How long does it take for the eggs to hatch? At what temperature will the eggs hatch?

the tank temp should be ok if they bred at the same temp to start. my cichlid eggs (cons) usually bust loose after three days, so im figuring they'll probably hatch or be eaten (if bunk) very soon. good luck
