Yup, they are schoolers. They can fly, too. Not very far, but about 30 ft...which would still be awesome to watch. I looked up some info about them when I got the e-mail.
The problem that I read about them is that they are hard to maintain in an aquarium. Picky eaters and whatnot. I came home with five. (I caught about 20, but that was too many.) Of the five, three died of stress. The other two just started eating two days ago. I'll get some more once I feel confident that these are going to survive.
I've read mixed things on how long they live. Some sites say they barely live to a year, some say they reach their final size at a year. I guess it would really depend upon other factors. Predation and such.
