thanks for the info... it is the second smallest fish in tank, being an 1" to 1.5" smaller then three other tank mates, at times it spends a lot of time on the move, but, is growing super fast, the base body color does swing at different times...Super dark.. doesn't look to healthy but based on color alone I would say female.
Too early to say though.
My females have also gotten this dark when angry/stressed/ or spawning (I can say that now!).Is it really this dark in person or is it just the lighting?
It looks very, very stressed.
I honestly can't guess at gender. Going off the dark color I'd say female. But that's only because I've seen my girl get dark when she is angry/stressed. My boy has never gotten even close to that dark.
