  We show that generic U(1) superfluids with a U(1)^3 anomaly feature universal
anomalous transport at low temperature. This universal behavior had been
encountered before for a class holographic models by performing explicit
computations: anomalous conductivities were found to either vanish or to be 1/3
of the value they present for ordinary fluids. In this note we argue in favor
of the fact that at zero temperature chiral conductivities are fully determined
by anomaly coefficients. We also compute them and show explicitly where their
particular value arises from. The proof is based on Ward Identities plus the
physical input that at zero temperature all the fluid is in its superfluid
component.
