Verrill's Encrusting Cup Coral

About

Found across the Indo-West Pacific and Indian Ocean, Polycyathus verrilli is a solitary or loosely colonial stony coral that tends to fly well under the radar compared to flashier LPS species. It belongs to a group of caryophyllid corals that produce small, cup-shaped skeletons, and in the aquarium it typically presents as a modest, textured polyp that rewards closer inspection rather than demanding attention from across the room. Because it shares no widely used common name distinct from its scientific name, it remains relatively obscure in the hobby despite being a genuine piece of reef biodiversity worth keeping. Intermediate care is a fair assessment. This is not a coral for someone still getting their first reef stable, but an experienced keeper with a dialed-in system should find it manageable. Moderate lighting and flow suit it well, and it is considered reef safe, posing no particular threat to neighbors. Source data on its specific behavior in captivity is limited, so approaching it with the same cautious patience you would give any less-documented LPS coral is sensible. If you encounter one, it is worth adding something a little different to a mature reef display.
