Thanks Pete, for the response. You’re the best!
The pregnant male finally got up off the bottom and found his female on the mangroves and hitched up with her. His breathing is still a bit quick but at least he moved from lying on the bottom. I’m trying to keep the kids from crowding the tank too much, and since the tank is in the living room it is not totally dark, as we are cooking in the adjacent kitchen, but all living room lights are out. I will give you an update in the morning!
