My actual adult female, has escaped about 5 times, two of them ended up in my fishtank and she ate half of my guppies, another time I was so worry, I couldn't find her and all the guppies were there so kinda worry me more, I put some plates with fish all over my house (at least in the first floor) then suddenly I heard some noises, Then I saw my snake at the top of my kitchen's door...what the...??? How did she get up my door?, and whe I was little I had a Radix that I found at my garden, she scaped and dessapeared for 3 months..I found her really skinny but she recovered very well...anyway, now I'm more careful.
But once I had a Red Kneed Tarantula, so we were on vacation and my mom gave the kyes of the house to my uncle, so he could feed the dogs, the fish and the birds...but probably my cousins were playing with the Tarantula (a little bit big, so I think they were just curious) , and they left the top of the cage all wrong so a few days later, guess what...no tarantula, anywhere 
so for 2 more nights all of us slept with one eye opened 
...we found the spider on the 2nd floor, on the TV room
