At a LFS today, just walking around, see a tank full of Bucktooth Tetras(Exodons), on the tank in big marker it said, "Extremely Aggresive" I have read about exodons on Pfish, with people having some success with them coexisting with their piranhas. But I wasn't sure about the whole idea, then I started bullshitting with the one employee, and he went and got some guppies and threw them in the tank. Now I have only seen my P eat in real life, these exodons destroyed the couple guppies he threw in there, it was the coolest thing ive seen in person. So I got two of them, they are a little smaller than flipper, they are still in the bag floating right now, Im gonna unleash them now and see what happens. Anyone else here have any luck w/ keeping these guys w/ your P's? I will try to snap some pics in case someone has never seen one before. By the way, I threw the pink convict back in the 10 gallon, she's beat up pretty bad, but I added some salt so I hope she recovers nicely.
