Aquavitro Coral Cutter 18cm
Clean cuts heal faster than snapped ones. The Aquavitro Coral Cutter is an 18 cm surgical-grade stainless steel fragging tool from Seachem's aquavitro line, built for cutting stony coral branches and trimming colonies to keep spacing, shape and growth under control in a reef tank. A clean shear through a branch leaves less crushed tissue at the cut than snapping it by hand, which matters for how quickly both the frag and the parent colony recover.
Key features
- Surgical-grade stainless steel - built to stay sharp and corrosion-free in saltwater use.
- 18 cm (7.25") straight-jaw cutter - long enough to reach into a display tank without submerging your hand up to the wrist.
- Clean, controlled cuts - a sheared branch heals and frags more reliably than one snapped or broken off by hand.
- Fresh and marine use - the same tool works for trimming freshwater stem plants as well as coral.

Which coral cutter do I need?
| Tool | Jaw | Best for |

Suitable for, and not suitable for
Suitable for: fragging stony corals for trade or propagation, trimming fast-growing colonies that are crowding their neighbours, and cutting stem plants in freshwater setups.
Not suitable for: cutting through thick, calcified coral base or rock - it's built for branch and tissue cuts, not as a rock saw, and forcing it through solid skeleton risks the jaws going out of alignment.
Care and maintenance
Rinse in fresh water and dry the blades after every use - salt left to dry on the jaws is what shortens the working life of any stainless steel aquarium tool, cutters included. There are no replaceable parts; a cutter that has gone out of alignment or lost its edge is replaced rather than serviced.
Safety
The jaws are sharp enough to cut coral skeleton and will cut skin just as easily - keep it closed and stored away from children when not in use, and handle it the same way you would any bladed tool.
Goes well with
- Aquavitro Crescent Coral Cutter 19cm - the curved-jaw companion for angles this straight cutter can't reach.
- Aquavitro Bond - to mount the frag you've just taken.
Warranty and delivery
Seachem's published documentation does not state a specific warranty term for this tool. Your rights under the Australian Consumer Law apply regardless, including remedy for a tool that fails or arrives faulty. It ships as a standard small item, no special freight handling required.
Common questions
Is this the same as the Crescent Coral Cutter?
No. This is the straight-jaw 18 cm version, for direct cuts on an accessible branch. The Crescent Coral Cutter has curved 19 cm jaws for reaching around branches or into a crowded colony.
Can I use this on rock, not just coral?
It's built for coral branches and plant stems, not as a rock-cutting tool. Forcing it through solid calcified base risks misaligning the jaws.
Will it rust in saltwater?
It's surgical-grade stainless steel, built for saltwater service, but any stainless tool lasts longer if it's rinsed in fresh water and dried after use rather than left wet.
Does it work in a freshwater planted tank too?
Yes - the same straight-jaw cutter suits trimming freshwater stem plants, not just marine coral.
