Scientific Name: Pterophyllum scalare
Common Name: Angelfish
Care Level: easy to moderately difficult
Size: 6 inches
pH Range: 6.0-7.5
Temperature Range: 24-30 degrees Celsius (76-86° F)
Origin: Amazon river, Brazil
Temperament: peaceful
Compatible Tankmates:
Angels are in general peaceful for cichlids and are suitable for community setups although be very careful in selecting their tankmates as they will often prey upon fish that will fit their mouths especially neon tetras which are their natural food in the wild.
Diet:
Omnivorous. They will eat anything you can provide them including commercial foods, bloodworms, earthworms and mosquito larva.
Tank Size for Adult: 20g.
Narrative:
Angelfish are one of the most popular cichlids in the aquarium trade. They have been around the aquarium trade for several decades already. They are often seen gracing the tank with their flamboyant fins. These fish are generally peaceful although they can often be aggressive during feeding time and may outstrip every tankmate for food.

Tall tanks are often best suited for these fish. The height must be at least 18 inches minimum. A 20g minimum is suggested for a breeding pair or a single adult but do make sure the dimensions provide ample space for them to swim around. The tank should be furnished with driftwood and heavy vegetation for them to seek refuge.

In the wild, angels often have black to brown vertical bars which help them camouflage among the reeds. Their habitat, in reality, barely has plants and mostly dominated by hairgrass (Eleocharis vivapara) along with tree roots. They are often seen stalking among the tall reeds looking for prey which comprises of insects, small fish and other aquatic creatures that will fit their mouths.

Angelfish have long been bred in captivity for decades so you will find that they are widely available around the trade in different strains ranging from the hardy koi, marble and zebra strains to the delicate double blacks. Genetics often play their role in the longevity of the angelfish strains. Veiltails and super veils are also widely available and require larger tanks than the minimum tank size given to provide space for them to be able to swim around well.

These fish are not sexually dimorphic until they spawn. Try to start a small group of young angelfish to grow on and let them pair off. They are rather choosy about their partners. Once the angelfish become sexually matured, they begin to choose their partner and once satisfied, they start choosing a spawning site and harass other tankmates as they defend their new territory.

Males are easily distinguished when you look at their vents which should be pointed and positioned forward whereas females have round edged vents and the vents are positioned backward. Anything else suggested to indicate their sexes such as humps on their heads and fins may not be perfectly accurate at all.

Male


Female


Breeding is not that difficult at all. After they chose their spawning spot, the female then starts laying her eggs on the spot and the male tries to release his milt to be able to fertilize the eggs. Sometimes, first time spawners will eat their eggs so you need to be patient when this happens. It takes time before the angelfish learn how to take care of their eggs properly. Sometimes two females will also pair off, not knowing their genders so it is wise to remove one of the females and let her choose another candidate as her partner.

Scientific Name: Pterophyllum altum
Common Name: Deep Angelfish
Care Level: moderately difficult
Size: 6 inches body diameter ; 15 inches dorsal and ventral fins height
pH Range: 6.0-7.5
Temperature Range: 24-30 degrees Celsius (76-86° F)
Origin: Rio Orinoco and Rio Negro in Brazil, Venezuela and Colombia
Temperament: peaceful
Compatible Tankmates:
Deep angelfish (Pterophyllum altum) are in general peaceful for cichlids and are suitable for community setups although be very careful in selecting their tankmates as they will often prey upon fish that will fit their mouths especially neon tetras which are their natural food in the wild.
Diet:
Omnivorous. Like the P. scalare, they will almost anything you can provide them provided these are in excellent health conditions.
Tank Size for Adult: 75g.
Narrative:
Since the early 1990s, the P. scalare has long been bred in captivity and still until present, very popular with dozens of strains available. There are two other species that have not been given as much attention as the P. scalare.

The word "altum" is a Latin word meaning "tall" and is quite appropriate for this species due to their body structure wherein their fins are unusually erect reaching 12-16 inches in height.

Pterophyllum altum is a close relative to the common freshwater angelfish known as Pterophyllum scalare and can be found in a relatively large area around Rio Orinoco and Rio Negro in Brazil, Venezuela and Colombia. It has long been thought and it is still a popular myth, even among experts that the altum angelfish (Pterophyllum altum) only can be found in Rio Orinoco however this is proven incorrect by studies of specimens in different museums that has been collected in a much larger area.

P. altum is easily distinguished from P. scalare by the sharp indentation just above their eyes, unusually erect dorsal and ventral fins and brown bars (rather than black which is the case for most P. scalare).

The altum angelfish are not widely available in the trade and command a very high price as these are very sensitive to water conditions especially when not acclimated properly. They are often shipped in vast numbers that the mortality rate is often very high and only a handful reach the dealer's tank alive although a few may succumb later on due to the stress factors brought by the transport. Add to that the fact these have never been bred in captivity at all.

Claims that these fish have been bred in captivity have yet to be proven true. Most of the time, the resulting angels claimed to be pure P. altum are actually crosses of P. scalare and P. altum rather than the pure specimen itself. Peruvian scalare angelfish are also sold as P. altum so you must be cautious when buying these fish to make sure you are not paying a high price for a wrong specimen.

Keeping these fish successfully is rewarding but may require efforts on your part. You must ensure the fish is acclimated properly and carefully as these are wild specimens that may be unable to tolerate the water conditions different from their native habitat. Tall tanks are recommended and should be no shorter than 24 inches. The tank must be furnished heavily with driftwoods and vegetative growth. The use of subdued lighting along with tannins are greatly suggested as these are very shy fish that will not tolerate bright lighting at all.

These fish are far different from P. scalare. The choice of tankmates may be more limited as their jaw structure is far wider and permits them to swallow even fish larger than how their mouths appear. These are best kept with fish that will not fit their mouths such as bronchis, plecos, discus, rams, deep-bodied tetras and apistogrammas.

Scientific Name: Pterophyllum leopoldi
Common Name: Longnosed Angelfish (formerly Pterophyllum dumerilli)
Care Level: easy
Size: 6 inches body diameter ; 15 inches dorsal and ventral fins height
pH Range: 6.0-7.5
Temperature Range: 24-30 degrees Celsius (76-86° F)
Origin: Solimões River, Amazon River, and Rupununi River
Temperament: peaceful
Compatible Tankmates:
Longnosed angelfish (Pterophyllum leopoldi) usually have nastier temperament compared to the other two angelfish. They may be suited i community setups but you have to carefully select their tankmates as they may become a menace and even eat small fish that fit their mouths.
Diet:
Omnivorous. Like the P. scalare and P. altum, they will almost anything you can provide them provided these are in excellent health conditions.
Tank Size for Adult: 20g.
Narrative:
Compared to the P. altum, these fish are found to be rather easy to keep. These are distinguished from the other two species by their slightly more elongated body structure and the black band which goes through the fish's eye does not sweep backwards towards the dorsal fin (as seen in P. scalare), but rather goes straight over the head and joins up on the other side. These are rarely seen in captivity so if you have an opportunity to grab these fish, be sure to be well prepared before you grab a bunch of these fish. They can be very expensive as well.
