Cycloseris cyclolites Propagation Guide
The small free-living disc coral Cycloseris cyclolites is a single solitary polyp; propagation rests on asexual regeneration of detached pieces, not multi-frag cutting.
Overview
Cycloseris cyclolites is a small disc coral in the family Fungiidae. Members of the genus Cycloseris are mostly solitary and free living, and unlike Fungia they are free living even as juveniles rather than starting attached. The body is a small round or oval disc with a central mouth surrounded by tentacles, occupying a single corallite.
Reproductive Mode
As a solitary fungiid, the coral reproduces both sexually and asexually. Because it is a single polyp resting freely on soft sediment, propagation in captivity centres on asexual regeneration of skeletal pieces rather than on dividing a colony.
Fragging / Asexual Propagation
Free-living fungiids are not cut into numerous frags like colonial corals. In Cycloseris, detached pieces of the disc can regenerate into new polyps, so propagation means encouraging a fragment to break away and heal into a new individual. The disc body and central single polyp limit how far a specimen can be subdivided.
Conditions for Propagation
A soft sand bed and gentle flow mirror the coral's natural setting on unconsolidated substrate and reduce abrasion on a healing fragment. Stable, low-nutrient water supports regeneration, and targeted feeding aids tissue recovery.
Sexual Reproduction
Sexual reproduction in the family proceeds by spawning gametes into the water column, with planktonic planula larvae settling to found new corals. This pathway is not practical for the home aquarist, leaving asexual regeneration as the workable method.
Common Challenges
Small disc corals are easily damaged by handling and can be smothered if they tumble into detritus or fall off rockwork. Sand abrasion and infection at any cut surface are the principal risks during regeneration.
