Hi guys, I have 2 males and females in my 20 gal, and I just came home to find that they had birthed while I was gone! Apparently the other fish ate most of the fry though, as I only found 2. These 2 though ar now too big for the top dwelling fish to eat. Should they be moved to a separate tank for me to feed them? Or can they fend for themselves at feeding tim? (fry are approximately 1/3 " in length).
