Hey guys. My Falco Hawkfish finally came into the lfs. He got what was called a pair in, how can you tell if it is truly a pair? I was under the impression that they live in groups, similar to Chloe fish, and were able to change their sex as well. I have done a Google, and didn't find much info on housing more thank one. Does anyone have any info on the subject. I plan on picking 1 if not both tmrw.
