The role of amino acids in coral feeding and growth.

Feeding

Similar to other animals, amino acids play important roles in the lives of corals, being essential to enzyme production, tissue growth and skeleton formation. In addition, amino acids are known to affect coral feeding behaviour. After the addition of frozen or live feeds to an aquarium, corals are often observed to extend their tentacles, a phenomenon which may be attributed to amino acids. Goreau et al. (1971) found that addition of the amino acids glycine, alanine or glutamate to the water resulted in opening of the mouth, tentacle extension, swelling of tissue and expulsion of digestive filaments for many scleractinian corals. Thus, these amino acids elicit the same feeding response as when zooplankton is supplied. It is possible that corals have receptors which recognize organic compounds, including amino acids. This ability to detect specific chemical compounds, known as chemotaxis, may allow coral polyps to recognize zooplankton and prepare for prey capture.

Yes I would 100% agree with you on that note.
Any bad effect to have polyp extension of sps corals out all day long without retraction?

No not really. Polyps will retract if they don't need the food.
