I’m hoping this will proves more helpful than my last post. The following are vents of three fish between 6” and 8” or so.

#1:


#2:


#3:


any thoughts? Thanks in advance.

Middle one looks male the other two female but could be wrong.

May I ask what you’re basing it on? I was pretty sure the first one was female, but had suspected #2 was also female while #3 was male. This was due to the second picture also having a U shaped vent whereas the third was more like two parentheses:

U vs. ( ) if that makes sense.

Looks female, female, male. But don't take my word for it.

Thanks for the input. I hope someone will come along that can give a more certain and definite answer.
