This is Martha she is about the same age as Fred. I'm not sure if its a he or she. She has been on a hunger strike for the past month and wont eat much but I will address that under diseases and disasters. She is about 2" at my best guess Here she is stalking the red jewel fry I put with her in hopes of getting her to eat.

shes beautiful fern

yes she is, wow

Here is an update, shes a good 4-5" now and getting to be quite a looker! Here's a few bad pics, she wouldn't stay still for good ones....
From above,
And here is both Fred and Martha

This is the remainder of her snack the other day...

Pretty cool.

she really turning around and lookin ggood...[b]

So what sex is Martha?

so any ideas on Marthas sex?

Definitely looks female. I've never seen a male vent that was rounded towards the anal fin. Normally a male will be pointed. Good chance Martha is named correctly.

If you can get a pic of Fred's vent, I can definitely tell you for sure. If they are different that is...
