I knew that, but I believe the question was about Nothobranchius per se. So 
perhaps Aphyobranchius also does not fit the category. So the question is what 
is the best measurement available for N. janpapi? If someone can send me an 
egg or two, I will measure it using the microscope. I do not discount the 
estimate made, just that I want to have the data on the same basis. My main reason 
for continuing to do this is that I still consider the egg diameter to be a 
fundamental characteristic of a species that is often neglected by species 
describers, mainly because they never see an egg. The caveat about egg diameters is 
that they are sometimes smaller from immature fish but stabilize at a narrow 
range for mature fish. Different collection sites for supposedly the same 
species have also shown differences that I worry about -- not enough to lose sleep 
over. For a table of egg sizes see my article in JAKA Jan/Feb 2000 Volume 33, 
No. 1
