I have a 10 inch Dovii and a 6 inch pair of Umbee. Love my Dovii he is like a watch dog bangs glass and eats like a horse. Umbee still small but.staring to really like them color wise I think Umbee are a real site to see, im noticing mu Male Umbee is more of a psycho at 6 innch, he like to stay in his corner alot but out of the blue he.will just swim full speed back and forth then body check the female lol. So far watching my umbee grow has been more interesting then my dovii, but dovii really start to bloom at 12 inch so I will see!
