The types of fish (your average clown, for example, can be fed once a day, whereas your average anthias needs food 4x or more daily; herbivores may require more raw volume of food simply because so much of it is roughage)
If you have any inverts that need supplemental feeding
What kind of food you're using (some are much richer nutritionally than others, there are different particle sizes, different ratios of food vs liquid, cube sizes, etc, AND different species will need different foods)
Be sure you thaw out the food before feeding. Never let food hit the bottom of tank or get into rock. I usally feed what they will eat in 2-3 minutes . Too much food can lead to problems with your water chemistry.
Live stock is 2 clowns, 4chromis,six line wrasse, a very small clown goby a algae Blenny , and a mandarin goby ,
I alternate feeding mysid and brine daily , I've dropped live pods , and sometime I target feed my corals. Oh and a cleaner shrimp. He goes to town on anything.
