I went out to Ocean city for a week, and while I was gone my om fed my fish. I came home and everything was as I left it, but 3 out of 3 of my sorority girls are missing.. coincidentally, all of the CTs? When I came home, the lid was open but idk if it was like that all week. I think the cat may have got them, but neither one ever shows intret in the tanks. Maybe they jumped out and the cat got them? they arent on the floor.
