![]() ![]() Around the age of three years, spawning frequency decreases and eventually ceases. In situations where the eggs are removed from the aquarium immediately after spawning, the pair is capable of spawning every seven to 10 days. scalare reaches sexual maturity at the age of six to 12 months or more. Upon the death or removal of one of the mated pair, breeders have experienced the total refusal of the remaining mate to pair up with any other angelfish and successfully breed with subsequent mates.ĭepending upon aquarium conditions, P. In addition, it is very difficult to accurately identify the sex of any individual until it is nearly ready to breed.Īngelfish pairs form long-term relationships where each individual will protect the other from threats and potential suitors. scalare is relatively easy to breed in the aquarium, although one of the results of generations of inbreeding is that many breeds have almost completely lost their rearing instincts, resulting in the tendency of the parents to eat their young. scalare only has two in true wild form throughout life.Īngelfish were bred in captivity for at least 30 years prior to P. leopoldi fry develop three to eight body stripes, with all but one to five fading away as they mature, whereas P. scalare's body does not show the stripe between the eye stripe and first complete body stripe at all, and the third stripe between the two main body stripes rarely extends downward more than a half inch, if even present. scalare, but a faint stripe shows between the eye stripe and the first complete body stripe and a third incomplete body stripe exists between the two main (complete) body stripes that extends three-fourths the length of the body. scalare is described as having 35–45 scales in a lateral row and a notched predorsal contour. leopoldi as having 29–35 scales in a lateral row and straight predorsal contour, whereas, P. New species of fish are discovered with increasing frequency, and, like P. ![]() ![]() Undescribed species may still exist in the Amazon Basin. Pterophyllum is derived from the Greek πτερον, pteron (fin/sail) and φυλλον, phyllon (leaf). Pterophyllum scalare ( Schultze, 1823) (freshwater angelfish)Īmazon Basin in Peru, Colombia, and Brazil Gosse, 1963)Īmazon River (between Manacapuru and Santarém), Essequibo River and Rupununi River. Orinoco River Basin and the Upper Rio Negro watershed in Southern Venezuela, Southeastern Colombia and extreme Northern Brazil The currently recognized species in this genus are: Image Pterophyllum should not be confused with marine angelfish, perciform fish found on shallow ocean reefs. As is the case for other cichlids, brood care is highly developed. Eggs are generally laid on a submerged log or a flattened leaf. All Pterophyllum species form monogamous pairs. Angelfish are ambush predators and prey on small fish and macroinvertebrates. Naturally occurring angelfish are frequently striped transversely, colouration which provides additional camouflage. This body shape allows them to hide among roots and plants, often on a vertical surface. The three species of Pterophyllum are unusually shaped for cichlids being greatly laterally compressed, with round bodies and elongated triangular dorsal and anal fins. All Pterophyllum species originate from the Amazon Basin, Orinoco Basin and various rivers in the Guiana Shield in tropical South America. Pterophyllum is a small genus of freshwater fish from the family Cichlidae known to most aquarists as angelfish. ![]()
