off topic: croaking tetra?

[swaldron@slip.net]

forgive the characin ignorance, but has anyone experience with a tetra
called the croaking? I have no idea what its scientific name or where its
from but looks a lot like like an elongate, narrow bodied emperor. The
males have the typical sparring behavior like emperors, they also do an
interesting stiff, low slung pectoral fin display, not unlike the
aggressive displays of certain sharks. anyone?
