Caught a big one (for me) - fishing pool - last trip to the Amazon. I think I had a picture in the presentation I did last year. I even had a picture of a much larger one caught by a local fisherman.
I bought one a couple of years ago. They are extremely pricey on the East coast. I was unable to get him to eat and he died after about a week. I had read prior to buying them that this could be a problem with small ones and to avoid buying them under 5". Guess I learned the hard way.
