i love my Urau Fernandez also. i only have 1 thanks to some weird bacteria infection that killed 1 of them 3 weeks after purchasing them. the 1 that i have left is doing great. i'll probably get a UV sometime down the road. i keep mine with 2 pissiticus, 1 geo altimira and 2 A. Heckeli. if some more pop up at my LFS i'll grap another one. they really need clean water and a temp of 84 degrees. awesome fish!
