Yea i think Sean had said that in one of his threads.

Feeding a Coral Reef Aquarium - S. Joshi

Excerpts:

Quote: Zooxanthelle are unicellular algae that live within the coral polyp, and are the primary producers that produce food energy via photosynthesis. The autotrophic mode of feeding involves the translocation of the photosynthetic products produced by the symbiotic zooxanthallae to the coral polyp tissues. Research has shown that the total energy demand cannot be met by photosynthesis alone. The corals spend energy for the following functions: respiration, mucus production, growth and reproduction. Respiration accounts for 60-70% of the energy budget of the coral, and for most hermatypic corals the ratio of gross photosynthesis to respiration is slightly greater than one. Hence corals need to provide the additional energy needs via other means.

Quote: Research in predatory feeding has shown that, even in corals with polyps active in the daytime, polyps hunt more efficiently at night.

would be an interesting experiment to conduct, sort of like a sleep deprivation study for corals.

All of my Sps have good polyp extension.. So matbe if I spot fed during the day that would be enough to deprive them of the night cycle...
Plants also go through respiration so maybe corals would benefit from a longer light cycle..
So the only down side I've seen so far is water temp and electric... And maybe hair algae..

	SPS Small Polyped Scleractinians - Sometimes known as Small Polyped Stony corals. These are hard corals that have extremely small polyps. They are typically on the difficult side and require Metal Halide lighting or dense Power Compact or T5 arrays. These corals are prized for their rareness and ability to be easily fragged into multiple colonies.

How do one "spot feed" SPS corals?

This thread is full of "innovations"

Some fish will definitely find 24 hour lights stressful, depending on what types of fish you have. Many wrasses have a definite sleep cycle where they bury themselves in the sand. I would say almost all vertebrate need a sleep cycle, you cant just keep swimming around for ever.
Can you test this in a special tank without fish? otherwise could you shade a portion of the tank to create a dark refuge for your fish?

Not really spot feed,,, but stop all current and give the corals some food by squirting food from a salifert syringe over the corals slowly.. I have been using the rinsed filter sock method of feeding my Sps the last couple of days.. I read up on this on a sight about gonipora feeding..
