Cortez Angelfish

<p>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. The Cortez Angelfish requires a large tank 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 (sessile invertebrates) and clam mantles.</p>

<p>This angelfish primarily feeds on sponges but is also supplemented by tunicates, algae, bryozoans, hydroids and eggs. In tank conditions, it should be provided with a diet of <em>Spirulina</em>, marine algae, shrimp and other meaty items, and high-quality angelfish preparations containing sponges.</p>

<p>Cortez angelfish often form pairs and have been observed spawning seasonally in similar manner; gametes are released in unison toward the surface, planktonic eggs floating with the current.</p>

<p>Cortez angelfish have a high tolerance for parasites and diseases in their immediate surroundings which make Cortez angelfish very sturdy fish to keep as pets. If not kept in tanks with optimum condition, they are susceptible to the common saltwater diseases such as Angelfish Virus, White Spot Disease, Velvet Disease, and Head and lateral line erosion (HLLE). </p>

<p>The Cortez angelfish is widely distributed in the eastern Pacific region. It ranges from the northern Gulf of California (from Puerto Peñasco, Mexico) in the north, to Peru in the south.</p>

<p>These angels are curious and friendly by nature. It has a tendency to become aggressive with other members of their own kind, other angels and other similarly marked fishes when provoked. They are solitary and fiercely territorial on the reef as adults. </p>

<p>When adding into new tanks, this species should be run through a freshwater bath to remove parasites and microbes. The tanks should have plenty of rock works for their hiding place when threatened. </p>
