I have two ropefish in my tank, Scyla and Decala. They are ALWAYS together, usually on top of each other, cuddling or whatever it is that they do. What I want to know is if it's possible to tell the difference between male and female. Decala is a bit more green than Scy. They're both the same size, and other than the color difference look exactly the same to me! So how can I tell the genders? And if I have two of the opposite sex...will I get lil baby ropefish? (That would be so cute!)
