I just got a rbp!! I am so excited!!! He is cool, 2".. I named him Barabus. He is quite active for a fish in a new tank: not hittiing any walls, not hiding in the corners. He is exploring the tank. He ate some flakes. What should I feed him? I guess beefheart and shrimp, which i will get tomorrow. Sometimes he hides in a little hideout, with is one large flat rock proped up by two small rocks. He sits underneath there and comes out to explore the tank. He is so cool. I have two more on order. If anyone could give me some tips about the first few weeks with piranhas i would be gratefull.
