Determining kribensis gender

[fisher_2]

Hey guys, i've got a trio of kribensis and i'm pretty sure i've got 2 females and 1 male, can someone take a look and confirm for me? i'm getting some aggression issues.

Yeah I'm pretty sure you're spot on with that.

1st looks male, dorsal fin's hard to make out though. 2nd is female, agree with you there. 3rd is male, you got that one right.

The first one's a poor pic, but I'm pretty sure it's female now, she's developed a bright cherry pink belly and it's bigger than the males.
