An unexpected "lifer". I had thought I would only encounter these in the mangroves, and have looked for them there before unsuccessfully. This was on a lagoon-facing slope, drifting in front of a small cave. I can't seem to make this into anything other than a Parioglossus dartfish, though am curious to hear from others about it since this isn't a group I've ever seen before and might have mis-identified it.
