Apistogramma Agassizii female or male

[ZanaZoola14]

I am wondering whether this fish is male or female. They are around an inch in length, and I believe I've seen them colour yellow at points; however, I don't have an image of this.

They have a faint black line through her tail fin; however, they also have black on their ventral fin. On their dorsal fin, there is a small line of orange/red, like a millimetre wide.

They were in this tub while I was sorting out the tank; I grabbed the photos before they were placed back into the tank.

They used to have a male; however, the male passed away after what I found out was internal parasites which I treated the tank for and have no signs of anymore. They've had free roam of the tank for a few months now. So I don't think if it was a he, they'd be a sneaker anymore.

Still too young/small to sex by me. They are really obese. At first I thought that they were some other species.

Alright, thanks, there were given a snack before all of this of blood worms, and I think they got most of it before anyone else in the tank could. I make sure not to feed whenever I notice that they are getting on the larger size.

I believe these are some better images of them.
