You're welcome... I love these sex my jag threads ...The problem with Jags is that most all look like females until they hit jag puberty..which as already mentioned by others is around 6 inches.. Yours is displaying a lot of black... Which may be just the way he is or maybe he's on a stress /attack /defense mode..... The one I took a pic of at the LFS kept squaring off against a red devil his size that was ruling a very large display tank they were in...That black bar between the eyes yours has my male gets that when I bother him when I clean algae from his tank... So I'm guessing with the others you have in there with him yours is not the alpha of the tank that he wants to be yet... Of course the only 100 percent for sure way to sex a fish is to vent it...on males it would look more like your pinky and on females like your thumb...you're the best judge since you see your fish everyday.. Just got to know what to look for...happy I could help and glad it looks like you are going to have what you wanted....
