[Killietalk] Comparing food sizes and values

["Brian Perkins" <btec11 at comcast_net>]

All,

I think that Sandy is looking for the smallest, most nutrition-packed food
available. If he had very small fry from a very small fish, that would only
eat very small food, what would you feed it? Remember, if it isn't small
enough they physically won't be able to get it in their mouths, but once
it's there it has to deliver nutrition to the small fish.

Poropanchax brichardi is the subject fish. The reports I am getting from
Europe are telling me that getting eggs from this fish is the easy part.
Getting the eggs to hatch is the next challenge, but getting the fry small
enough food is the stumbling block that seems to have stymied our European
friends working with this fish. 

I think then the question is: in the area of microfoods, small enough for
the fry to eat, what might be the best bet in terms of nutritional value?

The quote I got went something like "......the newly hatched young make
Betta fry look like whales...." Oh, and the fry are very sensitive to water
changes too. :O)

I wonder what food the Rainbow fish enthusiasts use for their truly small
babies?  Barry Cooper used to use Powdered Rotifers for the Pantanodon fry.
Presumably Bill Bishop uses something similar for his fish as well. Should
Sandy go with Green Water? Infusoria? Steffen Hellner suggested Spirulina
Powder?

Mach Fukada used to culture small marine creatures, I wonder what size they
were?

Hmmmm. Interesting fish.........

Hi Sandy,
?
You are asking for a comparison between apples and oranges. 
Green water is composed of single celled plants and animals like algae and
paramecia to smaller animals like rotifers.
