Goniopora tenuidens Propagation Guide
Propagating the slender-polyp flowerpot Goniopora tenuidens: fragging the 24-tentacle colony, slow recovery conditions, and the genus's longevity difficulty caveat.
Overview
Goniopora tenuidens is a flowerpot coral in the family Poritidae with thin, slender polyps. Its daisy-like polyps each bear around 24 tentacles around a central mouth, the trait distinguishing Goniopora from the twelve-tentacle Alveopora. It is among the slower-growing members of the genus.
Reproductive Mode
Goniopora reproduces sexually by spawning, with captive observations of hermaphroditic egg-and-sperm bundles and planula larvae settling within days, and asexually by budding and fragmentation.
Fragging / Asexual Propagation
Propagation is by cutting the colony into pieces that each retain living polyps and mounting them to heal. With its slow growth, recovery and regrowth take longer than in faster species, and growers report the best results when starting from fragged, aquacultured colonies rather than wild-collected ones.
- Cut the colony into pieces that each keep healthy slender polyps.
- Mount the frags and allow extra time for slow recovery.
- Begin with fragged or aquacultured stock for reliability.
Conditions for Propagation
Stable water with medium light and gentle flow, supported by periodic feeding, helps frags re-establish. Given the slow growth, patience and consistency matter more than for quicker corals.
Common Challenges
Goniopora has a long-standing reputation for slow decline in captivity, and the slow-growing tenuidens demands particularly stable, long-term care. Aquaculture and established frags have improved survival, but it remains an advanced coral.
