Flexo Crab – Fulling Mill
A crab pattern designed to catch permit, bonefish, triggerfish, bluefin trevally, and bumphead parrotfish. Crabs are extremely difficult to imitate with realism, but this fly uses a unique left-field approach. When thrown into salty water, the fly appears almost perfectly camouflaged, with the seabed visible through it. Permit and other aggressive fish like big bonefish and bluefin trevally often fall for this pattern because they lose sight of it and, when they do see it, fear it will vanish again, prompting them to rush and take it. The fly is tied on Tiemco 811 hooks, known for their strength and durability.
Available in Various Sizes and Shades
| Size | Shade |
|---|---|
| Size 6 | Dark Brown |

Used the Flexo Crab in a saltwater bay and caught a large permit within 20 minutes. The fly blended perfectly with the seabed and the fish attacked immediately when they saw it. Highly effective and realistic.
Jake Watson –
Fished with the Size 8 grayish brown version in the morning tide. Got a bonefish that took the fly right off the surface. The camouflage worked like magic and the fish seemed startled when they saw it.

The crab pattern is well-made and the hook holds up well. I’ve used it on multiple trips and it consistently draws fish, though it doesn’t work in very clear water.

Caught a bluefin trevally with the light brown size 10. The fly disappeared into the background and the fish didn’t realize it was there until it was too late. A game-changer for my saltwater fishing.
