feeding inverts

[Geedorah]

Hi!

I have recently set up a 24 gallon D-D nano.
I am running it "bare bottom" and have about 12kg of live rock.
I will be keeping it as an invert only system (hermits, various snails, shrimps, bristle stars) with some basic soft corals.
I was wondering what/how often should I feed the tank? I know in a normal system inverts such as these will feed off the left overs from any fish but since I wont be feeding fish I would like to know what/when I should be adding food to my tank?

Thanks!

Our hermits, cleaner shrimp and serpent stars will eat Hikari Marine A pellets. They also like frozen krill, frozen brine and frozen mysis.
