Does anyone use and recommend any foods (alive, freeze dried, produced, etc.) for really tiny (smaller than BBS to work) fry besides infusoria/green water?

[FONT=Verdana, Arial, serif]Apparently rotifers are around 100-200 microns in size. Is that too big for the smallest of fish larvae?

Is feeding freeze dried not a good idea? Even if you soak it in hot water before feeding out to get it fully saturated?

What size am I aiming for anyways? 5-50 microns?

I get paranoid with infusoria that there isn't enough food so I want something to supplement it for peace of mind and possibly improved health. I can't keep a green water culture going to save my life so that's not an answer unless a powdered spirulina, chollera mix is fine. But is that even suitable for carnivorous fish?

Thanks for input.

What are you feeding?

Vinegar eels, banana/walteror micro worms (three kinds there) are all good for very small fish. Vinegar eels are small enough for killie fry, so should be small enough for most. All three have the benefit of staying alive and active in the aquarium for a while, so won't foul it.
 
I'm talking about smaller fish than that. Larval fish, like peacock gudgeon sized fry.
 
I start tiny Danios, (Danio margaritatus, D erythromicron, D tinwini), on 5-50 micron Golden Pearls and green water. Next, screen newborn Moina which are smaller than both BBS / worms, (micro, walter, banana).

So basically anything around 5-50 microns. Thanks. :)
 
Kensfish sells golden pearls in several sizes, there's Hikari first bites, frozen rotifers (like you said, maybe too big?). I had no luck growing vinegar eels & microworms. Tabimin dissolves into tiny bits & might work for low tank strata fish like gudgeons. It's hard to find tiny foods that you can't over feed & vacuuming excess all the time is difficult. Any food you can grind to dust & feed tiny, frequent amounts can work.
 
Even I can keep vinegar eels and microworms alive! Do you just not keep up with it?

I hope I have some Apisto and rainbow fish and cory fry soon.
