Getting zebrafish fry to feed

[John Dower]

Hi there;

We have been encountering problems trying to get larval zebrafish to initiate feeding.
We are feeding the larvae on a diet of rotifers, which we have previously found to work
quite well with a variety of marine larvae.  Does anybody have any suggestions as to
what might be the problem?  We are using a high food concentration (about 10 rotifers/ml)
and so do not believe that to be the problem.

Any and all ideas welcome!

Thanks,
