Possibly this one all grown up: https://inaturalist.ala.org.au/observations/65528671 At the very least it was nearby enough that they'd have competed for the territory. We knew where it was sheltering for several weeks before this observation - but all we'd seen of it was a huge eye (with some very large suckers surrounding it) peering back at us through a small gap ... until today.

It was happily feeding, and not overly bothered about us, but there were three female Bluethroated Wrasse very persistently (and bravely!) hounding it closely, in much the same way that birds will band together to loudly draw attention to a cat slinking around their home territory.
