Gutting the Piranha catch. We went Piranha fishing on our first morning to catch our lunch. We all caught something, some were more successful than others. We fished sardine, amazon pike and red bellied piranha. I now want to take up fishing as a hobby (without the thrill factor that the fish might eat me). I can honestly say now that Ive slapped someone with a wet fish, as coordinating 6 people in one fishing boat is no easy feat. Oops.
