I think Eric's main point is that to really determine what a coral needs to
thrive, we can generalize for a starter guess, but it's not really dependent
on LPS or SPS type differentiation. Biologically they're the same thing
pretty much. What really makes the difference is what conditions the
particular specimen we have came from (and that's the information we're most
likely to not have unfortunately). Corals will, if given the chance, grow
in such a way that they have the maximum survival chance in the environment
they find themselves in. If they're suddenly moved to a totally different
environment, they have a problem because the form they've grown up with is
potentially no longer suitable for the conditions (and certainly isn't
optimal). A great example of this is seen with lighting. If you move a
bright purple acro from a tank with 400W 20KK lights to a tank with 400W
6.5KK lights, you will probably see the color change completely within a
month or so. That's the much touted photoadaptive response.
When talking about flow, one thing I learned (and it's the subject of the
thread I pulled that comment from) is that there's a big difference between
the flow from a strong ocean current (usually turbulent) and the flow a few
inches from a powerhead (lamellar). The flow from the powerhead will
probably blast the coral into the next life, even on a on/off timer.
If you're a marble head, then I am certainly one too :-).
