For the past couple of days, I have not seen my cardinals. Today the male presented himself at the glass with a big swollen mouth. He the proceeded to open his mouth to show me that it was full of eggs. The last time he was carrying eggs, something happened and I think he spit them out before they had a chance to hatch. Has anyone successfully raised these fry. I dont think I want to remove him from the tank, but i have alot of rock and hiding places. Anything I can do to help him out without removing him?
