maybe they’re oscars. An oscar IS like a baby piranha! My mother had some (present from my brother) and they had teeth and liked to eat raw ground beef. They ate all of the other fish in the tank.
I’m the youngest of 6. When I was in 6th grade and the sister just before me was in 8th grade (same parochial school) I saw that we were both using the same textbook but I forget what class it was for. I laughed at her, saying I was only in 6th grade and was using the same book. She said, “I don’t care because I understand it and can do the work”. I felt like a complete jerk and still feel bad about it to this day.
That’s exactly what I was thinking!
