Would there be any benefit to simulating a low tide situation? Is it just an adverse condition corals must endure, or does something beneficial come from it? Just a little out of the "glass" box thinking...
Corals and low tide

By low tide, do you mean aerial exposure?
If so, that is quite a stressful event and I can;t think of any benefit to it, not have I ever seen anything that would indicate it is beneficial in anyway...just remarkable that corals can survive it....and some don't.
If not, then I don't think a reduced depth for the duration of a tide makes much of a difference except in area where they are macrotidal, and then I don't think it would be necesary detrimental or beneficial. Just sort of the environment where those corals exist.

Eric,
Curious - is it possible that exposure to air may confer an added element of fitness to corals so exposed? Meaning, could prolonged exposure to air throughout the generations of any given individual and its descendents result in corals that respond "better" to overall stress - or likely just that particular stress? I have seen a lot of pictures of exposed corals and never have I seen a dead one in the bunch. You have seen it first-hand, so perhaps you can shed some brighter light on it. As for testing this hypothesis, compare two same species individuals from different portions of the reef - one exposed regularly and one never exposed to air. I know it would be somewhat hard to test this single characteristic, as UV exposure, current, and other physical parameters would confound results. Perhaps in captivity it would be easier? Anyone done this that you know of? Just thinking out loud again...
