Polyphyllia talpina
An elongated free-living fungiid whose axial furrow may become indistinct. Long, numerous tentacles emerge over the whole surface, and the grey, greenish or cream body is dotted with white tentacle tips.
Polyphyllia talpina is a free-living fungiid distributed across the Indo-Pacific. The colony is not attached to the substrate and is elongated, with a central axial furrow that may become indistinct. The septa are short and elliptical or petaloid, and long, numerous tentacles rise from the whole upper surface, so an expanded colony has the soft look of a sea cucumber. Colour is grey, greenish or cream, with characteristic white tentacle tips. It favours reef slopes where Fungia is common and is abundant through its range. It is zooxanthellate, drawing most of its nutrition from photosynthesis while also catching plankton with its tentacles. The skeleton is thin and light, so colonies are easily shifted by current or by other animals. As a scleractinian it is on CITES Appendix II, and the IUCN rates it Least Concern.

The ideal temperature for the Polyphyllia is 24〜26℃.
Origin
Indo-Pacific, common on reef slopes especially where Fungia is abundant.
Temperature
24〜26℃
Mainly nutrition from its zooxanthellae, with micro-plankton and zooplankton caught by its many tentacles.
Moderate light is enough; LiveAquaria lists fungiid plate corals as moderate-light corals. It does not need to sit under the brightest part of the tank.

Rest it on a fine sand bed. AlgaeBarn recommends low to moderate flow for fungiids. Its tentacles spread widely when expanded, so leave clearance from neighbouring corals.
Water 24-26C, specific gravity 1.023-1.025 (salinity 33-35 ppt), pH 8.1-8.4, KH 8-12, calcium 380-440 ppm, magnesium 1300-1400 ppm.
Its many tentacles make it an effective feeder; brine shrimp or micro-plankton dropped onto the tentacles are readily taken. It can also be kept on zooxanthellae alone.
The skeleton is thin and light, so it rolls in strong flow, and it rots if buried in sand or left upside down. As a scleractinian it is on CITES Appendix II and international trade requires permits. The English name tongue coral is also used for Herpolitha limax in the same family, so the two are easily confused in shops. This species can be told apart by the long tentacles rising from the entire skeleton surface, so confirm the scientific name.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Polyphyllia is 24〜26℃. Avoid sudden temperature changes and maintain a stable environment.
Polyphyllia feeds on: Mainly nutrition from its zooxanthellae, with micro-plankton and zooplankton caught by its many tentacles.. Aim for a balanced diet with appropriate feeding frequency.
