I just came back from a two week vacation and I noticed my red female betta was not in the tank. I checked under, around, and in the decor and even in the filter and on the floor and she's gone. She's too big for any of the fish to eat whole and I see no skeletons or fragments of her body. She wasn't flushed by the housekeeper because the bathroom up there still has crap from the last water change (before the fish went missing) in the toilet and she isn't in the trash. I'll try to call her after she gets done from work, but aside from that, anyone got any ideas?
