Too small to sex it yet. I bought it hoping for a female and then my male died. So who knows! It did kill it's sibling at 1.5", so I do know it's a hellion.
I'll snap some argentea photos right now. Just did a water change and the divider is out.
I believe the warmer water and small constant feedings led to the development of pitting on the little umbee's head which is visible above one eye and is on the opposite gill plate, so now it's in the 100 gallon with the argentea. Utterly fearless. Well over 3".
Thus ends my small stint at power feeding.
July 7th.
Compare the fish to the eggcrate in my first post and this photo. Today. 50 days I believe.
