Wow!! I bought mine from rapps around same time and my male is 4.5"+ and female is 4+. I had my first batch from them a couple months ago and they ate most all of them. I salvaged about a dozon and they are about .5" now. I would definately remove the other fish. My pair are in a 55 bythemselves and are getting ready to spawn again. I'll post pics soon of mine later tonite or tommorrow when I get home. Good luck with yours
