Zoanthid fragging involves cutting polyps from the colony and attaching them to new rock or plugs using glue or epoxy.
Zoanthids are colonial corals that can be easily propagated by fragging. This process involves cutting individual polyps from the main colony and attaching them to new surfaces where they will grow and form new colonies. Fragging zoas is a common practice among reef aquarium hobbyists to propagate these colorful corals, create new colonies, or trade with other enthusiasts.
Tools and Materials Needed
- Sharp scissors or bone cutters
- Razor blade or scalpel
- Cyanoacrylate gel glue or underwater epoxy
- New rock or frag plugs
- Clean container with tank water
- Turkey baster or pipette
Step-by-Step Fragging Process
- Remove the zoanthid colony from the tank and place it in a container with tank water
- Identify healthy polyps to be fragged, avoiding any with signs of disease
- Using scissors or bone cutters, cut the polyps away from the main colony, leaving a small piece of the mat attached
- Place the cut polyps in a separate container of tank water
- Prepare the new surface (rock or frag plug) by cleaning it and ensuring it's dry
- Apply a small amount of glue to the new surface
- Place the cut polyp on the glue, pressing gently to ensure adhesion
- Allow the glue to dry for a few minutes before returning the new frag to the tank
Care for New Frags
After fragging, new zoanthid frags should be placed in an area of the tank with moderate flow and lighting. Avoid direct, intense light initially. Monitor water parameters closely and maintain stable conditions. New frags may take several days to a week to fully open and begin growing. Be patient and avoid moving the frags once placed, as this can stress the polyps and slow their recovery.
Comparison of Fragging Methods
| Method | Difficulty | Success Rate | Best For |
|---|---|---|---|
| Direct Glue | Easy | High | Beginners, small frags |
| Epoxy Method | Medium | Very High | Larger frags, rocky substrates |
| Rubble Method | Easy | Medium | Multiple frags, grow-out systems |
Safety Precautions
When fragging zoanthids, it's crucial to take proper safety measures. Zoanthids contain palytoxin, a potent neurotoxin that can be harmful if it enters the bloodstream through cuts or mucous membranes. Always wear protective gloves, eye protection, and avoid touching your face while working with zoas. Work in a well-ventilated area and thoroughly wash your hands and tools after fragging. If you have any cuts or open wounds, avoid handling zoanthids altogether.
