# Z-Man FattyZ Worm: the floating stick worm that stands its tail up > Developed with Luke Clausen, the FattyZ is a 12.7 cm / 5 in ElaZtech worm that floats, so on a shaky head its tail stays up off the bottom. Rigs and limits. - Source : https://carnafish.com/en/leurres/z-man-fattyz-worm/ - Language : en-US - Updated : 2026-09-29 ## Spec sheet - Brand : Z-Man - Model : FattyZ Worm 5" - Type : Ribbed finesse stick worm - Target species : Bass, Perch - Size : 12.7 cm / 5 in - Weight : not published by the manufacturer, 6 baits per pack - Running depth : bottom and lower layer, 1 to 8 m / 3 to 26 ft depending on the head used - Retrieve speed : very slow, small shakes and long pauses - Action : natural ElaZtech buoyancy stands the tail up, ribs that quiver at the smallest movement - Rigging : shaky head first and foremost, also weedless Texas, wacky or neko rig - Colors : flaked green pumpkin in clear to lightly stained water, crawfish brown over hard bottom, black and blue in dark water Drop an ordinary worm onto a gravel bottom and it lies there like a shoelace. Drop a FattyZ and it stands up: tail pointing at the surface, head pinned down by the lead. That difference in posture looks like nothing in a photo; on a picky fish holding on a drop-off, it is the whole game. ## Why it stands up The answer is in the material. The FattyZ is moulded from ElaZtech, Z-Man's superplastic, which has **natural buoyancy** — unlike conventional salted plastisol, which sinks. Rigged on a shaky head, the bait is therefore pulled down at the front while the back wants to rise. The result is a vertical posture, nose down and tail up, exactly that of a worm or a larva grubbing in the substrate. That posture is held between movements, and that is where everything happens. A worm lying flat sends no signal at all during a pause; a FattyZ standing up keeps swaying gently with the current or with the simple movement of the line. The ribs moulded along the whole body, clearly visible in the photo, amplify that quiver: each ridge catches a little water and turns a micro-movement into a perceptible vibration. The bait is also **salt impregnated**, which lengthens the time a fish holds on to it. A bass that inhales a salted worm keeps it a fraction of a second longer before spitting it — long enough to set the hook. ## A power-finesse bait Z-Man developed the FattyZ with Luke Clausen, an FLW Tour professional who won the Bassmaster Classic in 2006 and the Forrest Wood Cup in 2004. The category it targets is *power finesse*: a slim, discreet bait fished on gear solid enough to pull a fish out of cover. In practice that means you do not fish a FattyZ on an ultralight rod and six-hundredths braid. A medium-light to medium rod, 10 to 12 lb braid and a 25 to 30 lb-class fluorocarbon leader are the baseline. You keep the subtlety of a slim worm while holding the reserve to turn a fish heading for a stump. > The pause is the retrieve. Count three seconds after each small shake, watching your line rather than your rod tip: nine bites out of ten show on the line before you feel them in the rod. ## The rigs that work ### Shaky head This is the priority use, and the manufacturer says so explicitly by pointing to its own Shaky HeadZ. Use a 3.5 to 7 g / 1/8 to 1/4 oz head depending on depth and wind. The bait carries a **moulded slot** in the body, visible in the photo near the thick end: it guides the hook point and eases penetration on the strike, since the wire does not have to drive through the full thickness of the plastic. ### Weedless Texas Offset hook with the point tucked into the back: the FattyZ travels through light vegetation and along branches without hanging up. ElaZtech buoyancy still helps here, since it lifts the rear of the body slightly even with no weight on it. ### Wacky and neko rigs Hooked through the middle on a wacky hook, the FattyZ falls folded into a V with both ends waving gently. On a neko rig — a lead nail pushed into the thick end and a hook through the upper third — you get the same vertical posture as on a shaky head, with a slower fall and more erratic behaviour. ### The classic mistake Over-working it. This is by far the number one error with this kind of bait. Plenty of anglers pull firmly out of swimbait reflex, lift the worm off the bottom and lose the vertical posture that is its whole point. The correct movement is a two or three centimetre shake of the wrist that never moves the jighead, followed by a long pause. You should be covering about half a metre a minute. ## Where and when The FattyZ is a tough-conditions bait: clear water, pressured fish, bright sunshine, an afternoon with no bite on hard lures. It shines on hard bottom — gravel, rock, dead wood — where the vertical posture reads well, and loses much of its interest over soft silt where the head sinks in. Across Europe it is also a very good perch bait along gravel-pit edges and canal rip-rap, as long as you drop the head size. For perch, 3.5 g is plenty and the bite registers as a simple heaviness in the slack line. ## A warning that matters ElaZtech is rated as up to ten times tougher than ordinary plastic: one FattyZ takes several fish without tearing at the hook slot. But the manufacturer is categorical on one point: **never mix ElaZtech baits with standard plastisol baits**. The two materials react chemically on contact and end up distorting and sticking to each other. A dedicated compartment in the box, or the original bag, and you will never meet the problem. One last factual point: the description gives **only the length, 5 in, and the pack count, six baits**. No unit weight is published. Watch the reading trap here: the 6 in the table is the pack quantity, not a mass in grams. ## Colors by water - **Clear to lightly stained water**: flaked green pumpkins, like the shade in the photo, a translucent green brown loaded with gold and black flake. This is the reference colour over hard bottom, readable without being loud. - **Gravel or rock bottom, clear water**: crawfish browns, which blend into the substrate and imitate the dominant prey in rocky areas. - **Dark water or low light**: black with blue flake, which is not trying to be seen as a colour but to cut a crisp silhouette. ## Where it sits in your box The FattyZ fills a precise slot: a long stick worm to be worked standing on hard bottom. Beside it, the [Z-Man TRD Ned Rig](https://carnafish.com/en/leurres/zman-trd-ned-rig/) plays the short, stubby card for even tougher fish, and the [Z-Man TRD TubeZ](https://carnafish.com/en/leurres/zman-trd-tubez/) brings a tube silhouette that spirals on the fall. If you want to carry the power-finesse idea through to a jig, the [Dirty Jigs Luke Clausen Finesse Jig](https://carnafish.com/en/leurres/dirty-jigs-luke-clausen-finesse-jig/) was designed by the same angler in the same spirit. That still leaves choosing the right zone, because a worm dropped in the wrong place will never make up for a bad read of the spot. That is exactly what [CarnaFish](https://carnafish.com/) is for: one photo of the swim, and the AI suggests a zone, a depth and a presentation type suited to the conditions of the day. To build the foundations, our [beginner's guide to bass fishing](https://carnafish.com/en/blog/peche-black-bass-debutant/) covers the classic holding spots and the tackle. ## Key takeaways - The natural buoyancy of ElaZtech stands the tail up: on a shaky head the bait works even at a standstill. - A moulded hook slot in the body makes the hook point drive home more easily on the strike. - Power finesse: a discreet bait, but gear solid enough to turn a fish in cover. - The description gives only 5 in and six baits per pack; the figure 6 is the pack count, not a weight. ## FAQ ### Does the FattyZ really float? Yes, the manufacturer states the natural buoyancy that is specific to ElaZtech, unlike conventional salted plastisol, which sinks. That is what lets the tail stand up off the bottom when the bait is rigged on a shaky head. ### What shaky head weight should I use? From 3.5 to 7 g / 1/8 to 1/4 oz depending on depth and wind, and more like 3.5 g for perch. Stay with the lightest head that keeps you in contact: too heavy a head flattens the vertical posture and removes the point of the bait. ### Can it be fished wacky style? Yes. Hooked through the middle on a wacky hook, it falls folded into a V with both ends waving. The neko rig, with a lead nail in the thick end, reproduces the vertical shaky-head posture with a slower fall. ### How much does a FattyZ weigh? The manufacturer publishes no unit weight: the table gives only the length, 5 in, and the pack count of six baits. This is a classic trap — the second figure is not a mass in grams. ### Why should ElaZtech not be mixed with other soft baits? Because the two materials react chemically on prolonged contact and end up distorting and sticking together. Z-Man states it explicitly. Store your ElaZtech in its original bag or in a separate compartment. ### Does the FattyZ work for perch? Very well, especially on rip-rap and gravel-pit margins, with a light jighead. The bite is often subtle, a mere sense of weight in the slack line rather than a sharp knock in the rod tip. --- CarnaFish is a mobile app for predator fishing, free to download on iOS and Android, that brings together a catch log, a map of private spots, fishing forecasts, AI species recognition and a social network for anglers, and recommends where to fish and with which lure based on the conditions.
