Coral Propagation
What is Coral Propagation?
Coral propagation refers to the process of reproducing and cultivating coral colonies, typically for conservation, research, or aquarium purposes. This practice involves carefully fragmenting corals and allowing them to grow into independent colonies. Coral propagation is often employed to support coral reef restoration efforts, enhance biodiversity, and mitigate the impact of environmental threats on natural coral populations. Methods of coral propagation include fragging, where coral fragments are secured to a substrate to encourage growth, and aquaculture techniques to cultivate corals in controlled environments. This sustainable approach aims to contribute to the health and resilience of coral ecosystems.

Coral fragging is a straightforward process that varies based on the type of coral. When fragging Small Polyped Stony (SPS) corals, a cutting tool is essential. However, for Soft Corals such as zoanthids, a simple box cutter suffices. Additionally, the process requires plugs or rocks onto which the coral fragments will be secured, along with a reliable adhesive. If a specialized coral glue is not preferred, cyanoacrylate gel glues, readily available at hardware or arts and craft stores, can serve as an alternative.
Small Polyped Stony (SPS) Coral Fragging Guide:
Materials needed: Cutter/Pliers, Paper Towel, Coral Glue, Coral Plug
-
Carefully select your SPS coral for fragging.
-
Use the cutter to trim the coral to the desired length, with a recommended size of 3/4". Even fragments as small as half an inch can grow into thriving colonies.
-
Wipe the cut-off part with a dry paper towel to ensure cleanliness.
-
Apply coral glue to secure the coral onto a plug. For larger pieces or colonies intended for attachment to rocks, epoxy can be used.
-
Exercise caution not to place different species of SPS corals in a container where they may come into contact, as this can result in stinging and potential harm, causing one to recede or die.
-
Allow the fragged coral to heal by leaving it in your tank. Typically, a week or two is sufficient, but for solid encrusting and stability, a month is considered ideal. This process promotes the healthy development of the coral fragments within the aquarium environment.
