Re: only male fry

[Mike & Diane Wise <apistowise@bewellnet.com>]

Lee,

What an interesting idea! It's one that Römer never tried. It would make 
an interesting experiment, especially if done at different 
temperature/pH values. One could even put part of a spawn in pairs and 
part in larger groups. In this way we can compare the differences 
environments make. Anyone willing to give it a try?
