My female guppy was about a week or 2 away from her due date. While I was a school she let her gaurd down and got caught in the filter and died WHY ME??? Now Charm wont have baby brothers and sisters. lol
She was most likely not well already. Fish generally don't get caught in filters unless they are already weak with the exception of fry, but I've even seen fry swim away from the filter intakes.
