Is there a way to tell the sex of these fish? :question: Or are they like clownfish and start off as males and then one of the pair becomes a female after a while? I bought one last week at the LFS, and went back as soon as they got another one in. And of course they didn't know who to tell the difference between males and females. I read that 2 males in a tank may fight. I have another tank, so if I have to separate them, it's no biggie, but I'd like to have a pair. Thanks again for any help!
