No, no, no, no, and no. This is not correct. 

Here's an excerpt from David K's message:

Note that he says "instar 2 or adults". I'm not up on the terminology here
but I believe instar 2 refers to second molt brine shrimp nauplii which if
you recall my post on this subject is the point at which the mouth forms
and enables the nauplii to begin eating.

They're feeding these things to larval marine fish. If baby clownfish can
eat
this so can your killifish fry.
