Sexing A. Macmasteri

[_bmah]

I picked up 2 A. Macmasteri from my LFS. I was pretty sure one was a male, the other was 50/50. Its looking more like a young/non-dominant male now but it does have more yellow to its body. I was hoping for confirmation as i am le3ss familiar with this species. All pictures are of the fish in question, other than the one with both where you can see the "forsure" male on the right in-front.

Based on dorsal fin tips, both are males. Sorry.
