When I got home the ornaments were knocked over and one of their bubble bars was disconnected. Two of my fish look really beaten up! They seem okay but I can't stand to look at the marks on them. After a water change and me adding some plants, I found some eggs stuck to the glass lid and dried up. They must have really had a wild night! Can the mating get that violent? They have mated before and it never used to be that way.
