I was recently looking at a picture of someones yellow con on another site and it had a much darker spot on its dorsal which was sort of outlined in electric blue. Much more pronounced dorsal markings than on the two I have in my grow out tank. I know it’s not 100% fool proof, but is this typically a sign that mine are male and the one I saw was female? I’ll include pictures of my two if anyone with some experience with them feels like going out on a limb.
