distinction between male and female of Keyhole (Cleithracara maronii)

[Fikret Celik]

I'm feeding the Keyhole two year. But pair with each other as the fish swims (Despite the lay eggs two times), unfortunately I have not puppies. Therefore I think my fish are both female or I thought my male fish probably vicious. In my opinion, I think both female. Could you help me please about sex discrimination in Keyhole? I wish you to help me...

This is male (probably),

That's the female (probably),

Waiting for help...

It is impossible to see any feature in these photos. The fish are totally out-of-focus. Sexing Keyholes is always difficult. Both sexes can have long pointed fins and be roughly the same size. The best way to sex them is by viewing the genital papillae when breeding: males - small and pointed; females - large and blunt.

Sorry, sir. A little bit about photo a rookie. But I will consider your views. Thank you...
