Lithophyllon undulatum
A mushroom-coral relative that stays attached to rock, spreading as encrusting sheets or flat plates with lobed edges. It has many mouths but usually no central one; deep green or brown in the north of its range, dark blue with white centres in the south.
Lithophyllon undulatum is a stony coral of the family Fungiidae; WoRMS also lists the Japanese name Minami-kawarasango. It occurs in the central Indo-Pacific on reefs and rocky shores. Most mushroom corals detach and lie free on the bottom as adults, but this species stays attached, spreading as encrusting sheets or flat plates with lobed margins. There is usually no central mouth; thin septo-costae stand out and many mouths are scattered over the surface. Colour is deep green or brown in the north of its range and dark blue with white corallite centres in the south (Corals of the World). The free-living mushroom corals on this site, such as Fungia, are kept on sand, whereas this species should be attached to rock. Reeflex rates it moderately easy, recommends at least 150 L and notes it is easy to propagate. Specialist shops in Japan stock it repeatedly.
The Lithophyllon Coral grows to Up to about 25 cm.
The ideal temperature for the Lithophyllon Coral is 24〜27℃.

Domestic law: Collecting in Japanese waters is governed by each prefecture's fisheries adjustment regulations, which differ by prefecture. Okinawa bans all collection of reef-building corals, including stony corals, and also bans possessing or selling illegally collected corals (cultured corals are exempt, and the prefecture advises buyers to confirm a coral is cultured, on an artificial base or tagged). Tokyo bans collection in the waters off Ogasawara Village. In marine park zones of national and quasi-national parks, taking designated animals and plants requires a permit (Natural Parks Act, Art. 22).
All stony corals (Scleractinia) are listed in CITES Appendix II (checked on Species+). International trade requires export permits, but no registration is needed to sell or transfer specimens within Japan.

It hosts zooxanthellae (Reeflex). LPS generally prefer low to moderate light (AlgaeBarn), so start at moderate levels.
It grows attached to rock, so settle it on a flat rock surface. Mushroom corals prefer low to moderate flow (AlgaeBarn).
24-27°C, salinity 33-35 ppt (SG 1.023-1.025); Reeflex gives 24-28°C.
Besides photosynthesis it uses dissolved nutrients and plankton (Reeflex). With many mouths, spread fine food across the surface.
Moderately easy and easy to propagate (Reeflex). Unlike free-living mushroom corals, it should not be left loose on the sand.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Lithophyllon Coral is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
Lithophyllon Coral typically reaches Up to about 25 cm as an adult. Size may vary depending on care conditions and individual genetics.
Lithophyllon Coral feeds on: Photosynthesis (zooxanthellae) plus plankton. Aim for a balanced diet with appropriate feeding frequency.
