Goniopora minor Propagation Guide
Propagating the small-polyp encrusting flowerpot Goniopora minor: fragging the 24-tentacle colony, recovery conditions, and the genus difficulty caveat.
Overview
Goniopora minor is a small-polyped, encrusting to colonial flowerpot coral in the family Poritidae. Like the rest of the genus, its daisy-like polyps each carry about 24 tentacles around a central mouth, distinguishing Goniopora from the twelve-tentacle Alveopora.
Reproductive Mode
Goniopora reproduces sexually through spawning, with captive observations of hermaphroditic egg-and-sperm release and planula larvae, and asexually through budding and fragmentation.
Fragging / Asexual Propagation
Because G. minor grows as an encrusting colony, propagation is done by cutting the encrusted base into sections that each retain living polyps, then mounting them. As elsewhere in the genus, outcomes vary and growers consistently recommend starting from fragged, aquacultured stock rather than wild colonies.
- Cut the encrusting colony into sections, each keeping live polyps.
- Mount the frags and let the cut tissue heal.
- Prefer fragged or aquacultured stock over wild-collected colonies.
Conditions for Propagation
Stable water with medium light and gentle flow, plus periodic feeding, supports recovery. Aquacultured frags settle into aquarium life more readily than fresh wild imports.
Common Challenges
Goniopora carries a documented history of slow decline in captivity. Improved aquaculture and fragged starter colonies have raised survival, but the genus stays demanding and benefits from stable, attentive husbandry.
