I think several researchers are now stating that corals actually get a fair percentage of their energy needs from food (as opposed to just light) so if you go fishless, feeding your corals would still be a good idea. SPS - maybe bbs or reefroids. Clams - phytoplankton. Corals with larger feeding tentacles usually need meatier fare, like mysis.
However, I would love to set up an experiment with identical lights & conditions & have one tank with feeding & the other without. Has anybody read any writeups on a similar expt?
Ruth, let us know what you end up doing & what are the results.
