[NHCOLL-L:4469] Choosing a preservative for cnidarians

[Frederick, Moretta RBCM:EX]

I'm interested in hearing people's opinions regarding the best way to
preserve cnidarians.  

Specifically, I am interested in longterm storage in Formalin vs.
Formalin-fixed then transferred to isopropanol/ethanol vs. fixing and
preserving in isopropanol/ethanol (no formalin).  I am currently most
interested in this information as it applies to the Hydrozoa and
particularily hyroid colonies but would also be interested to hear how
others are storing all cnidarian groups. 

Thanks in advance!
