Feeding Help!!!!

What do you guys recommend feeding in my tank on a daily basis?

 

I like the HikarI the best out of the three. But IMO it would be best to mix the 2nd and 3rd choices along with a good green marine algae w/garlic.
I think a good mix is better than just one kind.

 

do they eat a lot?

 

wow is your aquarium info correct??? the salinity looks really low for sw ( should be closer to 1.022-1.026) and it is way over stocked for a20g, with some of those fish alone growing too large for your size tank, sorry to be a downer

 

Yup, I have one of those asian tanks.
I keep my salinity at 1.018 because the fish will be easier to breath+elements some parasites.

 

I suggest you give away or sell your tank. Get a Bio cube.

 

...why?
