The Cortez Angel Fish is found around Magdalena Bay, Baja, Gulf of California, Peru and the Galapagos Islands. Where they live on coral reefs and sandy bays grazing on algae and sponges.
The coloration of the Cortez Angelfish varies markedly from juvenile to adult. The juvenile stage is black with yellow and blue semi-circular striping radiating from the tail. As an adult, the Cortez Angelfish is blue, with a pale, speckled mid-section and a swipe of vertical yellow just behind the head. The long, dorsal fin is a green-blue while the head is blue with yet another yellow vertical swipe just behind the eye.
They require a large aqiuarium, and should be the only angelfish in the tank, even as juveniles.
Not a good candidate for a reef tank, the Cortez Angelfish eat sponges, and will also consume stony and soft corals and clam mantles.
It should be provided with a diet of marine algae, shrimp and other meaty items, and foods containing sponges.
