This research presentation shows the growth at different salinities and temperatures. It also gives a feeding shedule:
DEVELOPMENT OF LARVAE CLOWNFISH AMPHIPRION CLARKII- EFFECT OF SALINITY AND TEMPERATURE
"... under the conditions used, the larval rearing of clownfish Amphiprion clarkii can be maximized at higher temperatures (30°C) and lower salinity (20 ‰)."
This should also apply to all other Amphiprion species and likely other genera as well.
