I know there are tons of these so my apologies but did my research before picking them out and I did my best to sex them in tank. So now they are home and I'm a little confused. So I shall post pics and would love opinions. One of them... The less dominant I couldn't get a good pick of in tank so I moved it to a baby food jar for one min. To get the pic, its normally not so dark and stressed the dark one I wanted you to be able to see the extended dorsal tips. Because this is why I'm a little confused about the sexes. Thanks for your opinions!
