[Coral-List] coral feeding questions

[Zac Forsman]

Great comments Charles!

  -I have one question though: the tanks at the
Waikiki Aquarium all have live rock/sand/gravel. 
Might these serve as refugia for populations of all
kinds of micro organisms that the corals could feed
on?  Increased nutrients might be used by the coral..
but they could also cause a bottom up trophic cascade
that benefit the coral.  Might also increase the
detritus or 'marine snow' in the tank.

I have one other question for Andrea:

   For the studies you mentioned that looked at
zooplankton, did they arrive at those conclusions by
looking at gut contents?  Would that bias the counts
towards critters with a hard carapace?


Is anyone aware of any other controlled feeding
studies out there?

-Just curious,  Zac
