Abstract: We investigate black holes formed by static perfect fluid with $p=\ensuremath{-}\ensuremath{\rho}/3$. These represent the black holes in ${S}_{3}$ and ${H}_{3}$ spatial geometries. There are three classes of black-hole solutions, two ${S}_{3}$ types and one ${H}_{3}$ type. The interesting solution is the ${S}_{3}$ type one, which possesses two singularities. One is at the north pole behind the horizon, and the other is naked at the south pole. The observers, however, are free from falling to the naked singularity. There are also nonstatic cosmological solutions in ${S}_{3}$ and ${H}_{3}$ and a singular static solution in ${H}_{3}$.
