Down to just the male, the female passed away today. She was doing really good, eating worms and ghost shrimp. I came home today and found her inside the sock filter on my sump. I have a 2" pvc inlet to my sump that stupid me never though about being an issue. Well when 3.5" ray swims by guess what happens. Feeling really stupid now. The inlet is now covered to protect the other. So much for a good deal!!!
