When I was younger I went fishing in crook by my house. After two hours of catching nothing, I decided to call it a wrap after a few quick swipes with the net to see if I could catch some tadpoles. I didn't catch any tadpoles- I caught a giant water bug. This thing was huge! Scared the crap out of me. So, what did I do? I took it home and put in my aquarium (back then all I had was a 10g). He held onto the airhose for my bubbler. Ever month I bought a dozen feeder goldfish and he would slowly eat them, one by one. One day, I forgot to put the lid back on... My mother freaked out and told me there was a bat flying around! Upon closer inspection, it was- The water bug.
