For the health and enjoyment of your fish, DO NOT over do it!
Over feeding is one of the leading causes of why your fish dies and do not thrive.
Most fish do well if you feed them twice a day. And please remember, more frequent and smaller ones are better.
If there is uneaten food left on the saltwater floating around, remove it with a siphon or net.
Not removing excess food will contribute to the change of your water chemistry that can affect the health of your fish.
Also, try to understand your fish dietary needs.
Some of your inhabitant might have different needs in terms of feeding.
Like corals! They do not move from your aquarium. So you will pretty much need to move the food to them.
You will need to feed them directly using a feeding stick.

Herbivores would be the vegetarians. But they would also need some sort of protien so feeding them meaty seafood would help. The most common herbivorous food includes:
Almost all saltwater aquarium fish are omnivores.
Feeding saltwater fish of this type will need a varied diet.
As a general rule, they need to somehow replicate their diet from their natural habitat in order to thrive.
Varied diet would be a combination of prepared and fresh food.
