correct my friend... more often than not, the unnaturally large food chunks will be regurgitated by the anemone. There are exceptions (very large or very aggressive species), butmost hobby use species and specimens should not be fed anything larger than mince/bits (mysid sized or smaller zooplankton substitutes).
Folks that feed large chunks and do not see their anemone regurgitate it later will generally watch their anemone "grow" over time. But what is really happening is that the starving anemone swells larger and larger in an attempt to pan for more light and trap more micro-matter on its mucous surface in the absence of adequate organismal feeding!
And after some months of this swelling, if not enough, the starving specimen often moves about the tank (much to the detriment of it or other cnidarians)
Angelfish... thanks for the very kind words. I very much enjoyed producing the new journal. In itself, it will be a great journey to publish ecclectic reef articles. My pleasure truly to share.
