I've been trying to figure out the sex of my Salvini for the past few days. I was almost sure it was a female but now I'm not so sure. Maybe you guys can help me out?
Based on the dorsal spot, I'd say female. The colors looks bland/washed out, but I think that's because of the low image quality and not the true color of the fish.
Yea the camera on my phone is crap. It's actually a much nicer color in person. But thanks for confirming what I thought. I suspect she's a female too because of the spot but I just wanted confirmation.
I agree that it is female. The spot on the operculum will likely come with age, although as japbart said, it is an inconsistent trait for sexing salvinis. Here is a sequence of shots of the same female salvini over a 7 months span. The middle pic is two months after the first pic - note the emergence of the spot on the gill and the increase on red on the belly and anal fin. The dorsal patch was always present, and got larger over time.
