>How do you sex Blue Rams? If a tree falls in forest does anybody hear ? What is the sound of one hand clapping :):)? You might want to look at dorsal fin height to body depth. Males should have taller dorsal fins with shorter body depth than females. Females should also be rounder in girth than males. The extended rays at the front of the dorsal fin should be longer in males. As others will no doubt chime in all of these features goes to pot with inbred domestic strains where these features can occur in both sexes. I would be interested to know of anyone's experience with sexing wild caught rams as they may be made available at a LFS. Andy samaroo@aracnet.net
