We provide a family of Non-Gaussian pure entangled states in a bipartite system as the eigen states of a quadratic Hamiltonian composed of the Einstein-Podolsky-and-Rosen-like operators. The ground state of the Hamiltonian corresponds to the two-mode-squeezed vacuum state, and belongs to the Gaussian states. In contrast, all of the excited states are Non-Gaussian states. A separable inequality maximally violated by the eigen states is derived.
