Clownfish spawning at lower temps

Has anyone experienced clownfish spawning at temps lower than 75*.  I have a friend who has ocellaris spawning at 73.5*.  Just curious.  He hasn't raised any so I don't know if they hatch.

At temps that low I'd expect their metabolism to be a lot slower than it is at 82°... They probably wouldn't spawn as often and eggs will take longer to hatch.

yes my clarkiis will spawn at 74  but only once every  3-4 months and eggs take near 10-12 days to hatch (far less 'consistent' timing)... while normally at 82 they spawn every 14 days, and takes them only 7 days to hatch. 
 
My ocellaris will spawn as well, but I can never seem to predict when their eggs will hatch when at a lower temp- typically miss them. 
 
EITHER WAY.... they are viable though, just take a long time getting there. 
 
I have even pulled a nest from 82, and 'stalled' a hatch by a 1-2 days by letting the temp drop in the bucket to 72 over night... then reheating the day you want to hatch.
