It does seem like a lot to me. I feed my 1 large sailfin(8 or so inches), 1 black ice snowflake clown, 1 blue damsel , 1 green brittle star, 1 snowflake eel, 2 mini maxis, 1 green bubble tip, 1 rock anemone, 1 orange spotted goby, 1 melanurus wrasse, 1 spotted mandarin, 1 scooter blenny, 1 lawnmower blenny, and a clown goby among the clean up crew, 1 full cube of mysis or brine depending on the day along with 1-2 ripped up pieces of krill(depending on size) mixed in and 3 full pieces of krill(2 for the snow flake eel to keep it away from eating my small fish and 1 for the bubble tip anemone every few days) I do a full sheet in a day for my tang. You should also add some kind of veggie for the coral beauty among others.
EDIT: Oops saw your post about the veggie.
