awww i'm sorry. i love that name though! i've always had that fear of doing that.....i am going to get some corys soon.....i'll be paranoid! that's why i am afraid to by cherry shrimp/ghost shrimp. they can be sucked up in the vac and in the intake! the other day one of my galaxy rasboras was getting very curious about the vacuum, and they are small.
but yes, it was an accident. i know it makes you feel sad...but at least you cared about him/the other fish enough, to be cleaning their home in the first place.
I've nearly sucked my guppies up a few times because they always want to check out the siphon. So sorry you had such a sad accident These things happen, as everybody else said. You can't blame yourself.
