About
A slender little fish with a yellow head and a white front half that warms into red and orange toward the tail. The second dorsal, anal and tail fins are red, trimmed with black.
Its signature is the first dorsal fin, which stands up like a tall flag and is famously flicked back and forth. It usually hovers just above its burrow in the sand and dives straight in at the first sign of danger.
In Fish Around
It flicks its tall dorsal fin as it holds still for a moment, then darts off in a quick, short burst.
