These mounds are indeed built by tilefish. I was in the Maldives in March, and noticed that they were abundant in depths of 50-80 m on the outer reef wall at North Huvadhoo.
I have attached a screen capture taken from ROV video. There were often multiple tilefish utilising a single mound.
I can probably find a better close-up of the fish if required.

Subject: [Coral-List] coral rubble mound builder?
I have seen mounds of coral rubble (ca. 30-40 cm diam; 15-20 cm high) on sandy channel bottom 17 to 30 m depth in Maldives.
I suspect tilefish but I don't recall seeing them doing the building.
A web search was suggestive but did not produce a conclusive result.
I'll supply a photo to anyone who has some knowledge of such mounds and an interest in seeing the photos.
