Debbie,

We have been processing whole Medaka and Guppy (size varies anywhere from
5mm x 1mm to 4cm x 2cm) for some time and we use roughly a 12 hour
processing protocol.  We have done a lot of research and development to get
the processing time just right.  I do not have our processing protocol with
me, but will be sure e-mail you a copy if you are interested.
