Scrawled filefish

Elongate compressed filefish with a small upturned mouth and long rounded tail.

Irregular blue lines and spots over a gray-brown body.

Most are around 22 in (55 cm).

Up to about 3.6 ft (110 cm) long and 6 lb (2.5 kg). Source: FishBase

It eats algae, seagrass, sea fans, colonial anemones, sea squirts and other small reef animals.

It lives on lagoon and outer reefs, and adults are often seen along deep slopes and reef drop-offs. It sometimes hangs under floating objects, and young ones ride weed rafts in the open ocean.

Found in Puerto Rico. Start on reef edges, ledges, rocky bottom, patch reefs and nearby sand/grass transitions; work the side with moving water and bait. Habitat reference:

Lagoons and outer reef slopes.

From 10 ft to 394 ft deep (3–120 m), usually 10 ft–66 ft (3–20 m).

Start near the bottom or reef edge where the species is observed; adjust until bites show the active level.

Lagoons and outer reef slopes. This is species-level habitat context, not proof for every linked area.

Fish legal open periods and favorable sea conditions; no single month works for every reef species.

Early/late light and moving water are good starting periods; some reef species feed well through the day or after dark.

Moderate moving water is often productive; excessive current may require more weight or a sheltered edge.

Choose sea state, wind and visibility that let you hold position and handle the fish safely. Avoid treating rough weather as a feeding advantage.

Small pieces of shrimp, squid, clam or cut bait are common starting baits for many reef species.

Small jigs, soft plastics, spoons or micro-jigs are common choices; use the smallest lure that reaches the zone.

Start with light/medium spinning gear, 10–15 lb line, 15–25 lb leader and a #2–1/0 hook or small jig.

About #4 to 2/0 is a practical starting range for small/medium reef fish; scale to mouth size and bait.

8–20 lb line is a common light-reef starting range; increase around sharp structure.

12–30 lb abrasion-resistant mono/fluorocarbon is a common start.

FAO documents traps. These include historical commercial or incidental catches; they are not ranked as best or assumed legal locally.

For an ordinary small fish, minimize handling and air exposure, support its body and use a dehooker. Species-specific hazards take precedence.

BigJoe does not classify Scrawled filefish as a routine food species from the current source set. That is not a claim that it is poisonous; before eating, confirm exact identification, lawful retention, documented local food use and current public-health advisories.

Not a common food fish — most anglers release it.

Ice it right away. Use a clean board and sharp knife; scale or skin only when appropriate, remove the viscera or fillet cleanly, trim damaged tissue/bloodline as desired, minimize warm-water exposure, and keep the edible portion cold. If the fish carries venomous spines, dangerous teeth or a toxin advisory, follow the safety warning before cleaning.

For routine cooked preparation, FDA seafood guidance uses 145°F (63°C) as the safe internal-temperature target for fish; flesh should be opaque and separate easily with a fork. Grilling, baking, broiling, steaming or pan-cooking can all work after the fish is positively identified, legally retained and cleared for applicable toxin/mercury advisories.

The Florida Museum reports ciguatera incidents associated with eating this species. This guide gives no recommendation to consume it.

No species-specific size, bag or season limits are listed here.

The catalog documents protected status in Cayman waters for this fishing group. There it is an encounter, not a fishing target. Other local statuses remain separate below.
