Notice my username is "fugupuff" I am a life long keeper and enjoy puffers immensely. I've kept probably every species of freshwater puffer fish with the exception of tetraodon schoutedeni, which is an enigmatic fish that has not been seen in the hobby for over 20 years, is it extinct? Well, when I saw these huge diodon hystrix cruising along the Hawaian shores I couldn't resist pulling one out and photographing it. I did release this one. I saw a pair even larger and dancing around each other, it was the most breath taking site to see this in the wild.
