Krib Problem?

[Scooper]

Sorry for the lack of inactivity but I've had a lot to do. Anyways, upon further inspection I've noticed that both of my kribs are male. My question is can I keep one and replace the other with a female or will she get killed? Both kribs are young, about 1.5-2 inches and one is just starting to color up.

If you want them to breed, I might add a couple of females and let them pair up on their own. Keep in mind that you will need some place to put the other male and female once a pair forms.

I was thinking of doing that but my tank is already past it's limit and I can't put anything into the 10 gallon because of the puffers. I was going to see if I could return one or both kribs and get a male and female instead. After that I would just hope for the best.
