In one of the previous articles of Fishes of Sahul (not able to provide you
the issue number at present), which if my memory serves me correctly Adrian
Tappin wrote, an experiment was conducted on the drying effects on
rainbowfish eggs. I am not sure whether this article is of use to you, but
let me know if you are interested in getting a copy. I probably could fax
it to you.
