So many people don't have lids on that can contain there fish, and i know a lot of people have lost fish because they managed to jump out even from a tiny hole.
Vote and then post what you have lost to jumping out or any near misses.
on three separate occasions i've had silver aro's jump. now i have 2 25pd plates from the gym on top of the glass and i have duck tape on the back of the tape holding the glass on tight.
