Guide by Captain Big Joe (Joe Arias)
At a glance
Most are around 14 in (35 cm).
From the surface down to 328 ft (100 m), usually in the top 66 ft (20 m).
Early morning, late afternoon and lower-light periods are common starts; tide/current changes can outweigh the clock.

Know it
Spot it, size it up and learn its habits.
- Identification
Oval flatfish with a notch above the nostril; males have a strong snout spine.
- Physical appearance
Blue rings cover the brown-gray eyed side.
- Typical size
Most are around 14 in (35 cm).
- Maximum size
Up to about 18 in (46 cm) long. Source: FishBase
- Diet
It eats mainly small fish, but also crustaceans and octopus.
- Behavior
It lives on clear sandy areas near mangroves, seagrass, coral or rubble, and is the most common flounder around coral reefs. It often lies partly buried in the sand.
Find it
Where, when and how deep to look.
- Where to find it
Found in Puerto Rico. Start in coastal channels, flats, beaches, sand/grass edges, passes or estuary mouths that match the species habitat, especially where current concentrates bait. Habitat reference:
- Habitat
Sandy shallows near reefs; also seagrass and mangroves.
- Depth
From the surface down to 328 ft (100 m), usually in the top 66 ft (20 m).
- Fishing depth
Work sandy/muddy bottom, channel edges and patches beside reef/seagrass; keep the bait/lure close to bottom.
- Fishing environments
Sandy shallows near reefs; also seagrass and mangroves. This is species-level habitat context, not proof for every linked area.
- Best season
Use current local reports and legal rules; choose days with manageable wind and good water conditions instead of relying on one universal month.
- Best time
Early morning, late afternoon and lower-light periods are common starts; tide/current changes can outweigh the clock.
- Best tides
Moving water around points, cuts, passes and troughs is a common trigger; watch where bait is concentrated.
- Best weather / conditions
Choose sea state, wind and visibility that let you hold position and handle the fish safely. Avoid treating rough weather as a feeding advantage.
Bait & gear
What to tie on and what to throw.
- Best bait
Shrimp, small crabs, sand fleas, mullet, sardines and cut bait are common inshore choices; match the bait to the species and bottom.
- Best artificial lures
Small bucktails, jigheads with soft plastics and small spoons are practical flatfish choices.
- Tackle setup
Start with a medium spinning rod, 10–15 lb braid/mono, 15–25 lb leader and a #1–2/0 hook or small jig; scale up for large tarpon/snook.
- Hook size
Roughly #1 to 4/0 is a common inshore bait range, scaled to bait and species; use stronger/larger hooks for tarpon-size fish.
- Line
8–20 lb line covers much inshore fishing; 20–40 lb is more appropriate around heavy cover or large tarpon/snook-class fish.
- Leader
10–30 lb fluorocarbon/mono is a common flats/inshore start; move to 40–80 lb around abrasive mouths, structure or large tarpon/snook.

Catch it
Step by step, from first cast to landing.
Step-by-step: how to catch it
- Start where the species is most likely to occur: Sandy shallows near reefs; also seagrass and mangroves.
- Rig for the habitat and current: Fish-finder/Carolina or light jig rig that keeps bait near bottom without excessive drag.
- Choose an offering that matches the fish and situation. Natural bait: Shrimp, small crabs, sand fleas, mullet, sardines and cut bait are common inshore choices; match the bait to the species and bottom. Lures/alternatives: Small bucktails, jigheads with soft plastics and small spoons are practical flatfish choices.
- Fish it with this starting approach: FAO documents hook-and-line, harpoons, nets, traps. These include historical commercial or incidental catches; they are not ranked as best or assumed legal locally. Presentation: Keep the presentation natural with the current; avoid over-weighting in shallow clear water and lead moving fish rather than landing on them.
- Use timing and water movement as adjustments, not guarantees. Time: Early morning, late afternoon and lower-light periods are common starts; tide/current changes can outweigh the clock. Tide/current: Moving water around points, cuts, passes and troughs is a common trigger; watch where bait is concentrated.

- Catch and release
For an ordinary small fish, minimize handling and air exposure, support its body and use a dehooker. Species-specific hazards take precedence.
Clean & cook
Is it good to eat, and how to prepare it.
- Edibility
Peacock flounder has documented food use in the BigJoe catalog/source set. Freshness matters — keep it on ice, and watch for any toxin or mercury advisory.
- Table quality
Very good eating: thin, delicate, sweet white fillets like any flounder. Pan-fry or bake gently so it does not dry out. One fish feeds one person.
- Cleaning
Keep legal catches on ice.
- Cooking suggestions
General idea: bake a portion and use a thermometer to check 63°C / 145°F. This is not a species-specific recipe.
Clean It & Choose Your Cut
Food safety: Food safety: keep seafood cold, prevent cross-contamination, wash hands and tools, and refrigerate promptly.
Recommended cuts
- Skin-on fillet
- Skinless fillet
- Whole cleaned fish
- Steaks for larger fish
Cleaning steps
- Keep the catch cold from the moment it is legally retained.
- Use a clean, stable cutting surface and a sharp dedicated fillet knife.
- Scale first if cooking the fish whole or keeping skin-on portions and the species has scales.
- For fillets, cut behind the gill plate toward the backbone, then follow the backbone toward the tail with controlled strokes.
- Trim ribs and remove pin bones where present; remove skin only if the recipe calls for it.
- Rinse only as needed to remove visible debris, then pat dry; keep the edible portion cold and cook or refrigerate promptly.
Anatomy varies by species. These are general finfish steps, not a species-specific anatomical guarantee.

Cooked/seared fish served over seasoned rice with cucumber, scallion and sesame.
Eating it raw? Follow FDA raw-seafood safety advice — fresh off the boat isn't enough.
For raw slices, freeze the fish first or use very fresh, well-iced fish.
