i recently got a 48x24x24 120 gallon aquarium. If I give a few fish away I could clear some space out and not have to put any of my current fish in my 120 gallon aqaurium. I was thinking about an umbee or dovii. But beacause the males get so massive I wanted a female. I was thinking about asking my LFS to get some of these so I could pick a female out and they could sell the rest. So i need a way to sex umbees and doviis. I wanted to be a way to sex it just by looking at it in an aquarium but if I have to i might be able to vent them.
