Crab Flies

The short answer: pick your crab by weight first and profile second. Bead-chain for skinny water and spooky fish, small dumbbells for the 1–3 ft flats, large dumbbells for pushing water and mid-column presentations. Color runs a distant third to sink rate.

Crab flies by species

Redfish

Redfish will eat almost any crab if it lands soft and sinks at the right speed for the water depth. Best sellers: Strong Arm Crab, Split Crab, our Strong Arm Grifter, and the Alphlexo Crab. Sizes 2 to 1/0.

Permit

Permit demand a natural drift, near-neutral buoyancy, and a soft landing. Merkin-style crabs, our Crab Royale, and small flexo patterns. Land 6–8 feet ahead and let the fly do the work. Size 1 to 2 for cruisers; size 4 for tailers in skinny water.

Bonefish

Small crabs with bead-chain eyes crush bonefish on hard-bottom flats. Downsize to size 4 or 6. The Split Crab in tan or olive is a bonefish crab you'll fish with confidence anywhere from the Bahamas to Belize.

Triggerfish, jacks, sheepshead

Weighted crabs in size 2 with a slow-fall profile. Colby's Tequila Twister Crab, Sheep Candy, and heavier merkins.

Weight cheat sheet

• Bead-chain eyes: 0–18 inches of water. Land soft, sink slow.
• Small (XS) dumbbell: 1–2 ft. The everyday redfish crab weight.
• Medium (S/M) dumbbell: 2–4 ft or when there's current.
• Large (L) dumbbell: 4+ ft, dirty water, or fast presentations.

Color, honestly

Tan and olive cover most days on most flats. Rust and orange for Louisiana marsh. Chartreuse when the water goes green. If the fish refuses, the answer is almost always size or weight — not color. We tie every FINATICS crab in a small color spread specifically because you shouldn't need eight versions of the same pattern.

How our crab flies are built

Every crab in this collection is tied on saltwater-grade hooks with materials chosen to survive multiple fish and multiple trips. We fish the exact patterns we sell — most of them were designed on Louisiana marsh water. If a fly can't take a redfish, a strike-and-miss, and another cast without falling apart, it doesn't go in the box.

Building a crab-only box? Start with three sizes of one pattern (say Strong Arm Crab in size 2, 4, and 1/0), then add one permit-specific fly (Merkin or Crab Royale) and one bonefish-size crab. Five flies gets you covered from Belize to the Louisiana marsh.
