Dear Listers!!!

Wow...it has been a long one month since the
debate started on the nutrients/algae/coral
complex and it was really informative...

Anyway..I dont know if this has already been
asked/discussed in the coral list....

But I am asking it again...do some coral species
eat at all?

When I ask this question..I mean..how many coral
species can live just like that (even wthout the
nutrient uptake form the surrounding water)

Is the coral-zooxanthellae complex
self-suffecient to an extent that there is no
need of external nutrient or food source...

How many coral species out  there can act as a
self-sustained perpetual machines?

I mean zooxanthellae producing energy by
photosynthesis, coral feeding exclusively on
old/dead and some zooxanthellae and then
transferring the endproduct to
zooxanthellae...and so on...

Is this process a viable option? if yes, then to
what extent?

Thanks for taking time and reading this and may
be correct me and give some comments....
