I had one beta that was in my room, and two other fish not sure what type of fish but they were definitely not Betta's that we left downstairs. This morning we woke up to find the two fish downstairs dead! That was a total shock, later that day, I went up stairs to feed my fish and she was dead too! I always feed them when needed, not too much of course, but how could they die the same day, they were in completely different rooms, and different types of fish. This seems so strange. Has anyone else had this happen to you, and if so do you know why? It would be very helpful! Thanks so Much!
