Pomacanthus (Arusetta) asfur (Purple Moon Angel)

As a writer in the sport diving and aquaristic hobbies I often hear, "Where's your favorite dive spot?", and "Where do the best fishes come from?". For marines my answer is immediate and confident, "the Red Sea". On a world-size map the area doesn't look big or important, but it is indeed; especially when you consider that it's coral reefs are continuous and intact.

So why haven't you heard much about this mythical area, or seen it's incredibly beautiful and tough livestock at your dealers? Mainly geography and cost. The countries that border the area are really only now beginning to develop their parts of the sea of "reeds" for tourism and ornamentals collection. That the sites are "out of the loop" of airline freight and most amenities results in the present high prices. But this is changing; the environment, living and not is being cherished and exploited as it should be; carefully, with an eye on sustainability. The result? More and lower cost for the source of hardy, tropical marines.

Eight of the nine species of angels coming out of the Red Sea have ranges extending outside the area, but from here they are more gorgeously colorful and suitable for captive oceans than anywhere else. Here are the marine angels of the Red Sea.

Classification:

The family Pomacanthidae consists of nine genera and seventy five (and growing) species. Angelfishes bear a stout spine on their gill cover able to get tangled in nets, puncture livestock and unwitting aquarists hands. This acanthus (= spine) on the operculum (= "pom") is an easy distinguishing mark between angels and the closely related Butterflyfishes.

All nine species of Red Sea angelfishes are imported into the trade, but only a few (Pomacanthus asfur, Pomacanthus maculosus) are regularly brought into the west. The others are better or only available from the region, but of considerably more expense due to related higher costs of collection, holding and transportation. But don't let me leave you with a false impression, the same species and the endemic (only found there) are BEST from the Red Sea; hardier and more beautiful than from anywhere else; well worth the extra charge.

Selection: General to Specific

Size:

Very generally; for small species get one that is 2-3 inches in length, the genera of larger angels, about 3-5 inches. Smaller individuals tend to be too beaten up in the processes of collection and transport and too-big one's adapt poorly, refusing food and displaying undesirable behaviors like bullying.

Reddening: 

Bloody color around the mouth, fins or body flanks is definitely a bad sign. I would not consider such a specimen for purchase. The scales should be flat, smooth and clean on the body.

Eating: 

Ask to see if the specimen is taking the kinds of foods you will be offering it. Ask to see if the specimen is taking the kinds of foods you will be offering it.

Location of Capture: 

Huh? "I thought we were talking about the Red Sea here?". We are; but how can you tell the animal you're looking at comes from there? Trust an invoice? The price? No; instead you should study up. You will be able to discern from appearances the differences yourself. These fishes are that much better looking. Look through reference works and/or take this magazine with you.

Cost: 

A few remarks here concerning pricing and sources of Red Sea livestock. For the lowest landed cost, you may well be tempted to "mail-order" these fishes (They ARE still expensive). Be prepared to pay for related costs, have your system ready and means of meeting the transport.

Alternatively, you may be able to coax a more local dealer into ordering and possibly tanking them for you, for a while. It may be necessary to front a sizeable, non-refundable deposit for this service, but well worth the cost of having them as your go-between.

The last scenario may exist for some lucky types who are near stores with standing inventories; these animals will most likely of the highest cost... however you will A) be better assured of their origins, B) have a leg to stand on in first person, for warrantee, and C) will be getting the most-aquarium acclimated specimens.

Environmental: Conditions

Habitat

The first and most important requirement for keeping these socially aggressive species is space; they must have as large a system as possible with as much cover/decor as practical. A good rule of thumb is a good ten gallons per inch of angel at presumed adult size. For the larger species we are obviously talking a very big tank. Cramping them without cover will only provoke fighting, hiding, and shortened lifespans.

Chemical/Physical

Seasoned (previously stocked system) water is best with angels. For Red Sea systems overall, a constant temperature in the mid seventies to low eighties, high specific gravity (1.025) and pH of 8.0-8.4 is ideal.

Filtration

Should be vigorous and heavy on aeration. Marine angelfishes are extra active, and need saturated oxygen levels.

Behavior:

Territoriality

Most species of marine angels are best kept one to a system (unless bought or collected as a pair, or harem). Further, similar appearing (color pattern and body shape) species rarely get along. Fighting is greatly reduced by undercrowding, and housing dissimilar species of decidedly different size. If you must have more than one angel species in a tank, do take care to introduce the smaller one(s) first, and keep your eyes on them.

Species other than angels generally leave angels well enough alone. Should your pomacanthid overly bully a tankmate, it is time to move that organism before it's too late.

Introduction/Acclimation

It is not unusual for a newly introduced specimen to immediately take cover and stay there for a few days! Neither is it uncommon for the newcomer to join right in with its tankmates. Don't let either end of this spectrum surprise or worry you. These fishes are individualistic, but almost all adjust after a short while.

Feeding/Foods/Nutrition: Types, Frequency, Amount, Wastes

This aspect of marine angel care vies with space in importance. In the wild many of these angels are coral, sponge and algal grazers; happily Red Sea angels have proven to adapt readily to substitute foodstuffs. Fresh or live clam, mussel, squid or shrimp, vegetable material and prepared angel foods (containing sponge material) are accepted by most with gusto. Some greenery, possibly with vitamin supplement should be offered daily.

Ideally some "live rock" would be cultured with these fishes, affording them the opportunity to feed on a mix of non-vertebrates and algae at their leisure. Marine angels should be fed a minimum of twice daily, preferably more often. I prefer to offer the meaty foods (chopped shrimp, crab, clam...) in the AM so I can remove it before retiring later; and a vegetable-based prepared mix in the later afternoon.

Disease:

Red Sea angelfishes are about as "specific pathogen free" as I've ever encountered from anywhere. Protozoans and flukes are rarely found on newly imported specimens, and they tend to stay clean. I encourage you to stick with standard prophylaxis (quarantine, dipping) to prevent introduction of infection.

Marine angels in general are easily susceptible to copper poisoning. If possible (it is), you should avoid treating them with copper compounds, instead relying on quarantine, dip and biological control methods to prevent disease.

Close:

Whichever angelfishes from the Red Sea you choose to invest in, it is money well spent. You are virtually assured of getting the hardiest of specimens, a long-term centerpiece, and something more; the knowledge that the individual has been collected with conscientious habitat and species-sustaining methods.
