did a water change and syphon yesterday and while the water was low i decided to take out my umbee to try get a vent shot. i'm spewin i didn't get a tape measure out before i netted my umbee, but i'd say it's definitely 7" maybe slightly bigger.
I think a shot of the entire fish would help me too sex your umbee. I've been told that if there's any black on their dorsal fins it indicates a female??? I'm sure others can confirm this and other things to look for w/o having to vent them.
