Yeah i recon it needs to be twice the size to properly sex it worth a try though lol. The patterning has really only just started to come out. I picked this jag because it was two to three times the size of its brothers an sisters im hoping for a monster jag
If you didn't just feed that jag before the picture was taken I'd say Female. Expect the colors to go through lots of changes. Very nice looking cichlid.
