Fungia paumotensis Propagation Guide
How the solitary, free-living plate coral Fungia paumotensis reproduces: anthocaulus regeneration and daughter polyps from injured skeleton, rather than conventional cut-fragging.
Overview
Fungia paumotensis is a member of the family Fungiidae, the mushroom or plate corals. Members of this family range from solitary individuals to colonial species, and most remain fully detached from the substrate in adulthood as free-living, mobile polyps. As a plate coral it is a single large polyp rather than a colony, which sets propagation apart from the methods used on branching or encrusting reef corals.
Reproductive Mode
Like other Fungia, the species attaches to rock as a juvenile and then detaches to live freely as a larger adult; juveniles leave a scar marking the former point of attachment. Reproduction occurs both sexually and asexually, and the asexual route is the basis of practical propagation.
Fragging / Asexual Propagation
Fungiids are not conventionally cut into multiple frags the way colonial LPS are. Instead, Fungia reproduce asexually: daughter polyps may form, and offspring develop from broken pieces of the skeleton, which show regeneration. In aquaria this is induced by deliberately injuring or removing tissue so that the remaining skeleton or detached fragment regenerates new polyps, a process tied to the anthocaulus stage of the life cycle.
Conditions for Propagation
Successful regeneration depends on a mature, stable system and clean water that supports healing of the cut skeleton. Because Fungia draw heavily on captured food, regenerating fragments benefit from regular feeding alongside their photosynthetic input.
Sexual Reproduction
Sexual reproduction in Fungiidae proceeds by release of gametes into the water column. Some mushroom corals, such as Fungia repanda and Ctenactis echinata, are able to change sex. Larval settlement and culture are not practical in a home aquarium, so asexual regeneration remains the realistic option for hobby propagation.
Common Challenges
Tissue recession from rough handling or sand abrasion is the main risk, and injured plate corals are prone to infection if water quality is poor. Regeneration of new polyps is slow, so propagation should be viewed as a long-term process rather than a routine fragging operation.
