Do I need to feed my corals?

[miston]

Do I need to feed my corals anything?

12 Gallon NanoCube
~12 lbs live rock
2 True Percula Clowns, 1 Yellow Watchman Goby, 1 Pistol Shrimp, 1 Fire Shrimp
branching Frogspawn
Green Star Polyps
1 Ricordia Yuma
1 Frilly Mushroom
Green Open Brain
pretty big cleanup crew (4 hermits, 4 ceriths, 7+ nassarius, 6 astreas)
chaeto w/ light in chamber 2

I change a little over a gallon of water a week, parameters are okay, though I just started feeding my fish, and I'm scared I'm over feeding, but so far so good.

I feed almost all of one frozen cube (either mysis, krill, or fortified brine) once a day. I'm trying to cut back, but those clowns look SO hungry!

I fed my green open brain a few mysis shrimp, how often do I need to do this? Do I need to do the same to my Frogspawn? If so how often?

The main question is, do I need to add any additives? (other than a 2 part calcium additive)

Nope, you don't need to feed any of them, though most may grow faster if you do feed a little (mysis, cyclopeeze, et al.) There's no fixed schedule to follow as all these will do fine without feedings, so feed at your discretion. I would feed less then more to keep up water quality.

And nope, no other additives if you are using 2 part solutions like Bionic or Cbalance.

I would keep feeding your open brain periodically. Mysis is great; I don't think you need to feed it more than once a week. Everything else will probably grow just fine without food.

You also MIGHT want to test for Magnesium, and dose that as well. I change 5 gallons a week on my 55 gallon, and for awhile my Magnesium was pretty low (although I haven't had to dose again for awhile.)
