For propagating zoanthids (zoas), choosing the right tools makes the process clean, fast, and safe for the coral. Because zoas often grow on a mat over irregular rock or are detached by chipping away a small piece of skeleton/plug, the ideal gear prioritizes surgical precision and strong, aquarium-safe bonding.
Best Bone Cutters for Zoas
When fragging zoas, you want a pair of sturdy cutters made of high-grade stainless steel to prevent rust in saltwater environments.
- Oceans Wonders Stainless Steel Stony Bone Cutter : Widely considered an industry standard in the hobby. Available at Bulk Reef Supply , these 6-inch cutters are made from 316 surgical stainless steel, offering a sharp edge to cleanly clip through encrusted frag plugs, aragonite disks, or small skeleton bases.
- SR Aquaristik Stainless Steel Coral Cutter : Another fantastic, durable option that provides great leverage and comes with a convenient protective case.
Tip: Always rinse your stainless steel cutters thoroughly in hot fresh water and dry them completely after every fragging session to prevent corrosion.
Best Glue Gel for Coral Propagation
You must use 100% cyanoacrylate gel glue. Regular super glue liquids are too runny and will wash away or damage the coral tissue; gels allow you to build a thick base that grabs onto wet surfaces.
- Seachem Reef Glue : An exceptional ethyl-cyanoacrylate gel that is significantly thicker than standard hobby glues, giving you maximum control with less mess. It comes in packaging designed to prevent premature drying. Available via Bulk Reef Supply.
- Two Little Fishies CorAffix Gel : A staple trusted reef glue with a thick consistency that skins over and bonds rapidly upon contact with water, making it very easy to secure zoa mats to plugs.
- Budget/Alternative option: Generic 100% cyanoacrylate gel (like Gorilla Glue Gel or Loctite Gel ) works chemically identical, just ensure it has no added accelerators or anti-fungal agents.
If you'd like, let me know:
- How your zoas are currently attached (on a large rock, loose on a mat, or on an old plug)
- Whether you need a step-by-step walkthrough for dipping and cutting safely (zoas can release palytoxin, so safety gear advice is helpful)
I can give you a customized propagation guide for your specific setup.

For fragging zoanthids (zoas), I'd go with a quality stainless-steel bone cutter and a thick, aquarium-safe cyanoacrylate gel. You don't need expensive coral-propagation equipment, but you do want a cutter that makes clean cuts and glue that holds frags securely to plugs or rubble.
One important distinction: zoas grow on a mat of tissue called the coenenchyme. The best cutting tool depends on whether you're separating individual polyps, cutting a mat off a rock, or splitting a larger colony.
My top picks
1. Best budget bone cutter
Tamsco Instruments Coral Cutter 5.5-inch
$18
Chewy
A good starter cutter for small coral skeletons and breaking away bits of rock. For zoas specifically, I'd use it to trim the rock or plug, rather than cut directly through the soft polyp tissue.
My pick for an affordable, general-purpose cutter.
2. Best for tougher rock and skeletons
Tamsco Heavy Duty Coral Cutter, Cow Horn Jaws
$42
Chewy
The heavier-duty option if you also frag stony corals or need to break apart suitable rock sections. It's more tool than you need for simply trimming a few zoa polyps.
3. Best glue gel for frag plugs
BSI IC-Gel Insta-Cure
$19.99
Lush Corals listing
My first choice for mounting zoa-covered rubble onto ceramic plugs. Its extra-thick cyanoacrylate formula stays put instead of running all over the place.
4. Best alternative glue
Seachem Reef Glue
$14.99
Petco listing
A convenient reef-specific cyanoacrylate gel for attaching frags to plugs and rock. A good alternative if IC-Gel isn't available locally.
Prices are from the listings found during this search and can change.
What I'd actually use to frag zoas
A bone cutter is useful, but a sharp disposable scalpel or razor blade is usually better for cutting the zoanthid mat itself. If the colony is attached to a rock, trim a small piece of the rock with the cutter or a chisel, then glue that piece onto a frag plug.
Sharp scalpel or replaceable-blade knife
For cutting the soft zoanthid mat cleanly.
Ceramic frag plugs or rubble
For mounting and growing out each new frag.
Important zoa safety precautions
Zoanthids and related palythoa corals can contain palytoxin, which can cause severe poisoning.
- Wear nitrile gloves and sealed, splash-protective eye goggles.
- Never boil zoas-covered rock, use heat, or cut in a way that creates spray or airborne droplets.
- Work in a well-ventilated area, keep your face away from the coral, and avoid touching your face.
- Keep tools dedicated to aquarium use, and clean them safely afterward.
My bottom line: I'd buy the affordable Tamsco cutter, BSI IC-Gel, a sharp scalpel, and ceramic plugs. That's a sensible starter setup without spending money on heavy-duty equipment you may not need.
One question that would help me fine-tune the tool recommendation: Are your zoas growing on a removable frag plug, a small piece of rubble, or a big piece of live rock?
Google AI ModeOct 16, 2026
The top-rated bone cutters and cyanoacrylate glue gels for fragging zoanthids and palythoa corals are heavy-duty stainless-steel surgical bone cutters and thick-viscosity ethyl cyanoacrylate gels.
For zoas, the goal is making a clean slice through the mat or base rock and securing the fragile polyp tightly to a new plug without letting the glue bubble over the polyp face.
Top-Rated Bone Cutters & Scalpels
- Dive/Surgical Stainless Steel Coral Bone Cutters (e.g., Two Little Fishies, Innovative Marine , or generic 316-grade stainless steel diagonal/bone cutters): These are essential if your zoas are attached to a hard frag disc, branch, or piece of live rock that needs clipping. High-grade stainless steel resists saltwater corrosion, though rinsing and drying them after every use is mandatory.
- Disposable Surgical Scalpels (Size #11 or #12): Many expert reefers prefer a sharp scalpel or fresh razor blade over bone cutters when zoas are on a thin mat. Slicing cleanly through the mat minimizes tissue damage compared to crushing or snapping rock with pliers.
Top-Rated Glue Gels
Widely regarded as a gold standard in the reef hobby, this extra-thick cyanoacrylate paste comes in a squeezable tube rather than a rigid bottle. It holds its shape underwater instantly and allows precise placement without running all over the zoanthid polyp.
Another top choice specifically formulated for aquarium use, featuring a thick gel consistency that bonds rapidly upon contact with saltwater and remains completely non-toxic to sensitive soft corals.
Gel-type Super Glue (100% Cyanoacrylate)Generic or brand-name cyanoacrylate gels work well as long as "gel" is specified (thin super glue will run and smother the zoa polyps).
If you'd like, let me know:
- Are your zoas growing on frag plugs, large rocks, or flexible matting?
- Do you need tips on dip protocols (like Lugol's iodine) post-fragging to prevent infection?
I can provide a step-by-step walkthrough tailored to your setup.

For fragging zoanthids (zoas), I’d prioritize precision cutters, a sharp scalpel, and an extra-thick cyanoacrylate gel glue. One important distinction: zoas are soft corals, so bone cutters are most useful for cutting the rock or frag plug they’re attached to—not for cutting through the polyps themselves. Bulk Reef Supply recommends keeping as much zoanthid tissue intact as possible and using scissors for smaller tissue cuts.
Best tools and glue for zoa fragging
1. Best all-around bone cutters: BRS SPS Coral Bone Cutter
About $13–$20 depending on model
Good for breaking apart small sections of rock or plug material beneath zoa colonies. BRS lists several sizes, including a 5-inch model and a curved-jaw version.
2. Best for trimming zoa mats: Oceans Wonders Soft Coral Cutting Scissors
Listed at about $6
A budget-friendly choice for making controlled cuts through soft tissue when you need to separate a small section of colony. Keep as much of the underlying substrate as practical.
3. Best premium-style glue gel: BSI IC-Gel Insta Cure
$19.99
(5.0/5)
One listed seller; only 1 review
A very thick cyanoacrylate gel that holds its shape and is useful for attaching small rock pieces or frag plugs. The high viscosity helps when mounting frags on uneven surfaces.
4. Best value glue: BRS Extra Thick Gel Super Glue
$7.99
A practical option for routine fragging, with a thick consistency for securing coral-bearing rubble to plugs. A good first purchase if you don't need a large bulk bottle.
5. Best alternative: Seachem Reef Glue
Listed at $14.99 for 0.7 fl oz
A convenient aquarium-specific gel adhesive designed to bond frags to rock or plugs, including underwater. Worth comparing if your local aquarium store stocks it.
What I'd buy for a home zoa fragging setup
Item Recommendation Bone cutters BRS 5-inch SPS Coral Bone Cutter Tissue-cutting tool Sharp coral scissors or a replaceable-blade scalpel Glue BRS Extra Thick Gel for value, or BSI IC-Gel for a thicker consistency Mounts Ceramic frag plugs or clean rubble rock Safety gear Chemical-resistant gloves and splash-proof eye protection My pick: Start with the BRS bone cutters, soft coral scissors, and BRS Extra Thick Gel. You don't need an expensive fragging kit just to propagate zoas.
Important safety precautions for zoanthids
Zoanthids and related palythoas can contain palytoxin, which can cause severe illness.
- Wear gloves and splash-proof eye protection.
- Never boil, microwave, or use hot water on zoanthid-covered rock.
- Avoid creating aerosols or splashes, and don't use a power tool on zoas.
- Keep tools and fragging water away from food-preparation areas.
- Rinse and dry reusable tools after use, and keep them dedicated to aquarium work.
BRS specifically emphasizes protective equipment and minimizing tissue cuts when fragging zoas.
One question that would help narrow down the best cutter: Are your zoas growing on individual frag plugs, or are you trying to cut them off a larger piece of live rock? The best tool differs quite a bit between those two jobs.
