Help sexing one of my "Blue Steel".

[Aviant]

Hi all, I just recently bought another Blue Steel my job just got from a new shipment - Apart from all the others that came, this one looked from what I've read to be a female. I went and introduced the 2nd one into the tank, but it's clearly bigger than my male, it chases him around and doesnt look so healthy now that I have it. I just wanted to know if it COULD be a male or if its really a female (hoping it is).

Here's a picture of the male I have:

And this is the 'female' I got:

If someone could help me figure out what sex the 2nd one is, I'd be truly appreciative.


Edit: To me, it looks like they're both males just from their line. The 2nd one being more faded. I'd like to have a 2nd opinion from someone else though. Thank you.

The photos don't show features well enough for me to determine sex. Photos that show the fins extended would help. Also, how large are these fish?

Hmm, It may be hard to get that photo especially of the second one. Apparently it developed Ich so it's fins are clamped. I'm treating the tank already so hopefully in two days I'll be able to get better results. The first one is really tiny. I want to say an inch. The second one is about 1.5 inches.

Right now both are too young/small for me to sex.
