  We study anomalous charged fluid in $2n$-dimensions ($n\geq 2$) up to
sub-leading derivative order. Only the effect of gauge anomaly is important at
this order. Using the Euclidean partition function formalism, we find the
constraints on different sub-leading order transport coefficients appearing in
parity-even and odd sectors of the fluid. We introduce a new mechanism to count
different fluid data at arbitrary derivative order. We show that only the
knowledge of independent scalar-data is sufficient to find the constraints. In
appendix we further extend this analysis to obtain fluid data at
sub-sub-leading order (where both gauge and gravitational anomaly contribute)
for parity-odd fluid.
