I'm not an expert in fish histology, but embryos, being very fragile,
would be best processed with minimal times.  I'm assuming you will be
doing these in paraffin.  After being properly fixed, I would process
them, in ethanol, 70%, 80%, 95%, absolute, absolute + xylene, xylene (2
changes / 15 minutes each), then paraffin, 58 C, 4 changes, 30 minutes
each change. I prefer xylenes, not the substitutes, but if that's what
you use... I use this protocol for mouse livers and any other small,
fragile tissues that come through here and it works wonderfully.  

Hope this helps
