Apisto Cacatuodies sexing confirmation

[Haunting-Walrus7199]

I am looking for help sexing my Apisto Cacatuoides. In the picture with both fish I'm confident the right more colorful fish is male. I believe the left fish is female. The left fish is also singled out in the other two photos. Based on the round caudal fin, lack of tall rays on the front of the dorsal fin, and black front edges of the pelvic fins I believe this one is female. I am keeping them in a 20 tall aquarium with guppies. I have had the male for about a month with no issues and the (hopefully) female for a day. I am hoping to get them to breed eventually.

Thanks for the help.

Welcome to the sight, I believe you are right about the female.
