This topic has got to be the one for which I have heard the most polarized answers.
A beginner like me is VERY confused to hear from an
LFS employee that he likes to feed a lot and often, and then read in books that you should feed sparingly. My accumulated experience is in nano tanks, where feeding is sparse or with penalty.
Amphibious brings experience, and good advice in the concept of "thrive" versus "survive" - but I assume a tank's sustainability has a lot to do with how well a system can eliminate excess nutrients. Those with
DSB's,
Refugiums, more effective
skimmers and better practices may have better luck with generous portioning than those with more meager systems and discipline.
I have 1 Ocellaris Clown (1.5"), 1 Spotted Cardinal (1.5") 1 Cleaner Shrimp and several Nassarius. I feed 1/4 cube frozen food every day or two. I feel as if I feed lightly, but my system's
nitrates (~15ppm) tell me otherwise. I attribute this mainly to a lack of
DSB and
Refugium, although I added some Chaetomorpha recently.
