Half-Banded Seaperch
The Half-Banded Seaperch is easy to identify from the Banded Seaperch for that reason: It's band margins are indistinct and half-formed whereas the Banded Seaperch has very defined margins, almost always with four complete bands. They are a bit more social than the Banded version and there are often a few found in the same section of the reef.
