More food = more poop = more to clean up.
I feed my fish once everyday. I find that flakes provide an excellent healthy diet, leave little mess as it floats better in the water column allowing the fish to eat most or all of it. However, not all fish will eat flake food at first or even ever. Your luck may vary. I also feed frozen foods about every 3 days, mostly for my tooth coral and other meat eatering corals.
I have 2 tanks, a 30 gal and a 55 gal. 30gal as the following fish: Green banded goby, stripeless clown, yellow assesor, green chromis, greissengeri goby, 2 spiny head blennys, two-spot blenny. The 55gal has the following fish: pair of adult black percs, scopas tang, coral beauty angel, mandarin dragnet(after 2 years, still only eats pods), purple firefish. I put two pinches of flake food in my 55 and 1 pinch in my 30 when feeding flakes. When I feed frozen, both tanks share a frozen cube of mysis. about 1/3 in the 30 and the rest in the 55. I used to put algea sheets in my 55 for the tang and angel, but I recent aquired a mantis shrimp (unintentially) and he b*tch ate all my hermits and snails. So my tang and angel are on algea patrol and doing well I might add. I just wish they ate more to be honest, things are getting out of control.
