  Pisces-Eridanus (Psc-Eri), a nearby ($d$ $\simeq$ 80-226 pc) stellar stream
stretching across $\approx$120 degrees of the sky, was recently discovered with
Gaia data. The stream was claimed to be $\approx$1 Gyr old, which would make it
an exceptional discovery for stellar astrophysics, as star clusters of that age
are rare and tend to be distant, limiting their utility as benchmark samples.
We test this old age for Psc-Eri in two ways. First, we compare the rotation
periods for 101 low-mass members (measured using time series photometry from
the Transiting Exoplanet Survey Satellite, TESS) to those of well-studied open
clusters. Second, we identify 34 new high-mass candidate members, including the
notable stars $\lambda$ Tauri (an Algol-type eclipsing binary) and HD 1160
(host to a directly imaged object near the hydrogen-burning limit). We conduct
an isochronal analysis of the color--magnitude data for these highest-mass
members, again comparing our results to those for open clusters. Both analyses
show that the stream has an age consistent with that of the Pleiades, i.e.,
$\approx$120 Myr. This makes the Psc-Eri stream an exciting source of young
benchmarkable stars and, potentially, exoplanets located in a more diffuse
environment that is distinct from that of the Pleiades and of other dense star
clusters.
