Cortez angelfish in Los Cabos

How to recognize it

Adults have a deep, flat, almost rectangular body. They are gray to gray-brown, darker toward the front, with small dark spots and faint pale arcs on the sides. Look for a broad yellow band from the nape down behind the cheek, and a narrower, black-edged yellow band just behind the pectoral fin. The rear of the body is charcoal, the tail is pale yellowish and the dorsal and anal fins have blue edges and usually end in filaments. Juveniles are black with six curved yellow bars on the head, body and tail, with narrow blue bars between them.

Biology

The Cortez angelfish lives only in the tropical eastern Pacific, from southern Baja and the Gulf of California to Peru, including the oceanic islands. It is a resident of rocky reefs from 1 to 50 m deep. Adults usually travel in pairs or small loose groups and range widely over the reef, while juveniles are solitary and defend a small territory.

Adults feed by day on the bottom, mainly on sponges, plus tunicates, algae, bryozoans, hydroids and fish eggs. Pairs appear to be monogamous. Breeding runs from midsummer to early fall, and juveniles are most common from August through November. Small juveniles work as cleaners, picking parasites off other fish.

Seeing them from the boat

The Cortez angelfish is a fish for snorkelers and divers, not anglers. It lives on rocky reefs around Los Cabos, often in pairs, and the black-and-yellow juveniles hide in rocky shallows. It is not a sport fish.

It has a small mouth and eats sponges, so it is rarely hooked. If one ever comes up on a bait, unhook it gently and put it straight back: it is protected in Mexico. Sport fishing is not allowed inside Cabo Pulmo National Park.

Rules & conservation

Protected in Mexico. If one is ever hooked, release it right away.

Don't confuse it with

The king angelfish (Holacanthus passer) is velvety blue-gray with a single narrow white bar on the side and a yellow tail; its juveniles are orange in front and brown behind, with thin blue bars, not the bold curved yellow bars of a young Cortez angelfish. The Cortez angelfish is bigger and gray, with yellow bands behind the head and behind the pectoral fin.
