Help sexing a Thai silk FH

[anzo1993]

Hello, I was at my LFS and I noticed they got a batch of Thai silks in with very nice colors around the 3.5 inch mark, I picked up one of the nicer ones and was wondering if anyone had any guess on male or female? I know abit young but all my previous Flowerhorns by the 3 inch mark I was able to tell but this one I’m finding abit difficult

Propably not the answer you are looking for, but when they are in the bag or you transfer it to your tank its a good opportunity to vent them if you aren't sure. A picture is never wrong to have.
