Pomacanthus

Pomacanthus zonipectus

(Gill, 1862)

Cortez Angelfish

Not Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Eastern Pacific Ocean: Gulf of California/Sea of Cortez south to Columbia.

Size: 18 inches (45 cm)

Natural Environment: Inhabits sandy areas adjacent to rocky reefs at depths of 10 to over 100 feet (3 – 30 m) and feeds on sponges and tunicates.

General Husbandry: The juvenile is quite pretty with it being overall brownish black with six vertical bright yellow bands that begin on the face and end at the peduncle. It’s dorsal and pelvic fins are edged in bright blue. As for the adult, rarely ever collected because its far less colorful, it has an overall greyish body with its central portion paler grey, and two vertical bars just aft of the head, one darkish yellow, which is somewhat enlarged in the breast area, and one greyish white bar.

Juveniles are often seen in the trade, and should be introduced into well-established fish-only aquariums with lots of live rock and cave areas and offered numerous daily feedings so as to quickly acclimate it to its surroundings. Like many others in this genus, their captive diet should consist of a wide variety of frozen foods including fortified brine shrimp, mysis, and especially those containing sponge matter/angelfish food preparations and continued to be offered at least several times daily thereafter. Furthermore, flake foods, and especially those containing Spirulina and/or Nori should be also offered, along with fresh broccoli and macroalgae, as ‘greens’ make up a portion of this species diet, especially the juveniles and subadults.

Depending upon its tankmates, juveniles may be somewhat shy when first entering the aquarium, and may hide in caves and crevices. But as time passes, will become more outgoing and begin to establish its territory. As they grow into adulthood, they become quite feisty, therefore should be the last angelfish to be added to the aquarium.

Taxonomy:

    Order: Perciformes

    Suborder: Percoidei

    Family: Pomacanthidae

    Genus: Pomacanthus

FYI: Keeping more than one genus of angelfishes in the same aquarium is possible, yet depends upon several aspects. The following suggested circumstances are just that, possibilities that when heeded and adjusted to actual aquarium conditions ‘may’ make multiple angelfish collections feasible.

Aquarium size – the larger the better.

Species from the same genus should not be in the same aquarium.

The smallest and most docile genus species should be the first introduced with the largest and most malicious the last to be added.

Do not place similar coloration species in the same aquarium.

Those already in the aquarium should be well fed before adding a newcomer.

Have sufficient hiding places/rocky caves.

Do not overfeed meaty foods, especially juveniles, as it may lead to a fatty deposit around the liver that could stop production of vitamin A. This could cause blindness, often referred to as nutritional blindness.

Keep in mind all angels have cheekspines at the edge of their gill cover; therefore use caution when handling and also avoid using a net to capture it, as it may become stuck or tangled in the net and become damaged when removed.
