I have a patch of cabomba that does a similar thing, but I know the reason.
The way the currents flow in the tank, the cabomba is in a down-draft, which
forces the stems outward for a few inches until the current is weaker, at
which point it grows up towards the light again. It makes for an
interesting "star" effect.
