Should I worry
Enjoy it
Harmless. Nearly always released, which is why there are still plenty.

Nothing else looks like it. Seven long spines rise from the back like a rooster’s comb, and when a school drives baitfish into the surf the combs cut the surface in a line. People book flights for this.

Where you’ll see it

Along rocky points, beaches and river mouths the length of the coast, often in water shallow enough to wade. Boats out of Coco and the Papagayo marinas target them year round; the dry season is the classic time.

What to know

Roosterfish are an inshore predator with no commercial value and a poor table reputation, which is the best thing that ever happened to them: the whole culture around them is catch and release. A fish of 20 kilos is a good one, and larger exist. Keep the fight short and get it back in the water fast, and there will be one for the next person.

Questions people ask about this one

What is the best fish to catch in Guanacaste?

Ask anyone who fishes here and the answer is the roosterfish. It hunts close to shore along rocky points and beaches, it fights hard, and the Papagayo coast is one of the best places in the world for it. Almost every one caught is released.

Wondering what else is out there?

Ask me on the call. I'll tell you what actually shows up in a Coco garden, what to do about it, and the one guy everyone rings when there's a boa in the roof.
