Considering two molecular state assumptions, i.e. S-wave $\bar{ \Lambda}-K^-$ and S-wave $\bar{ \Sigma}^0-K^-$ molecular states, we study the possible decays of $\bar N_X(1625)$ that include $\bar N_X(1625)\to K^{ -}\bar{ \Lambda}, \pi^{ 0}\bar{ p}, \eta\bar{ p}, \pi^{ -}\bar{ n}$. Our results indicate: (1) if $\bar N_{ X}(1625)$ is $\bar{ \Lambda}-K^-$ molecular state, $K^{ -}\bar{ \Lambda}$ is the main decay modes of $\bar N_{ X}(1625)$, and the branching ratios of the rest decay modes are tiny; (2) if $\bar N_{ X}(1625)$ is $\bar{ \Sigma}^0-K^-$ molecular state, the branching ratio of $\bar N_{ X}(1625)\to K^{ -}\bar{ \Lambda}$ is one or two order smaller than that of $\bar N_{ X}(1625)\to \pi^{ 0}\bar{ p}, \eta\bar{ p}, \pi^{ -}\bar{ n}$. Thus the search for $\bar N_X(1625)\to \pi^{ 0}\bar{ p}, \eta\bar{ p}, \pi^{ -}\bar{ n}$ will be helpful to shed light on the nature of $\bar N_X(1625)$.
