By: Nic Paquette Thanks in large part to Dr. Joanne Norton much is known about the genetics of angelfish. Dr Norton’s work, published between May 1982 and March 1994 in Freshwater and Marine Aquarium magazine, still stands as the cornerstone of what we know today. Similar to the genetics of all vertebrate organisms angelfish carry two copies of each gene, one which is inherited maternally, one which is inherited paternally.
Steel Blue is also sometimes called Metallic Blue. This colour has a metallic iridescence when compared to the Royal Blue Betta. Steel Blue results from the allele combination blbl. Steel Blue, Green, Royal Blue, Green and Turquoise Bettas have an interesting genetic inheritance pattern based on the Bl / bl alleles that show incomplete dominance and determine iridescence. Crossings: Steel Blue x Steel Blue gives 100% Steel Blue off-spring ; Green x Green gives 100% Green; Green x Steel Blue gives all Royal Blue ; Royal Blue x Royal Blue gives 50% Royal, 25% Steel , 25% Green ; Green x Royal Blue gives 50% Royal, 50% Green .
Siamese fighters are individualists; there's no other aquarium fish fairly like them. Nearly every aquarist possesses a minimum of one male, even if he has no intention of breeding. The extraordinary beauty of the Siamese fighter is sufficient to warrant it a place of honour in any community tank. The male, when fully grown, develops a long flowing anal fin, a high dorsal fin, along with a big flowing rounded tail.

The Siamese fighting fish ( Betta splendens , pron.: / ˈ b ɛ t ə / ) also known as Betta , (particularly in the US [ citation needed ] ), is a popular species of freshwater aquarium fish . The name of the genus is derived from ikan bettah, taken from a local dialect of Malay . [ 1 ] The wild ancestors of this fish are native to the rice paddies of Thailand , Malaysia , Cambodia and Vietnam and are called pla-kad (lit. biting fish) in Thai or trey krem in Khmer . [ edit ] Description B. splendens usually grow to an overall length of about 3 inches, including fins. Although known for their brilliant colors and large, flowing fins, the natural coloration of B. splendens is a dull green and brown, and the fins of wild specimens are relatively short. Brilliantly colored and longer finned varieties (i.e.

The rummy-nose tetra , Hemigrammus rhodostomus , is a species of tropical freshwater characin fish originating in South America , popular among fishkeepers as an aquarium fish. One of many small tetras belonging to the same genus, it is a 5 cm (2 in) long fish when fully grown, and is a long established favourite among tropical fishkeepers. The fish is one of several very similar species including Hemigrammus bleheri , and Petitella georgiae , and it is possible that more recently collected specimens available in the aquarium trade are members of one or other of these similar species. The common name applied to most of these fishes is "rummy-nose tetra", though other common names are in circulation (such as "firehead tetra" for H. bleheri , according to FishBase ). [ edit ] Physical description
Red nose tetras are peaceful but delicate fish that attain a length of about 1.5 inch at maturity. The nose and forehead is deep red, and also the body silvery tending to olive on the back with a light yellow on the belly. A dark stripe runs down the side of the body increasing in width as it extends into the tail.
Serpae tetras are one species of the genus Hyphessobrycon , and are now known as Hyphessobrycon eques . These South American tropical characids are popular aquarium fishes, often identified as "red minor tetras". They are found in the wild in the Madeira and Guaporé regions of the Amazon river , and in upper Paraguay .
Food The Marbled Hatchet fish eats a variety of live foods including mosquito larvae, brine shrimp and bloodworms. Sexing There are no differences between males and females unless the females are heavy with eggs. The eggs are visible through her thin body. Breeding These egg layers are not easily bred in the aquarium , but if there is successful spawning the adults should be removed soon after the eggs are laid. Lifespan The Marbled Hatchet will live for up to 5 years.
The cardinal tetra , Paracheirodon axelrodi , is a freshwater fish of the characin family (family Characidae ) of order Characiformes . It is native to the upper Orinoco and Negro Rivers in South America. Growing to about 3 cm (1.25 in) total length, the cardinal tetra has the striking iridescent blue line characteristic of the Paracheirodon species laterally bisecting the fish , with the body below this line being vivid red in color , hence the name " cardinal tetra ". The cardinal tetra's appearance is similar to that of the closely related neon tetra , with which it is often confused; the neon's red coloration extends only about halfway to the nose , and the neon's blue stripe is a less vibrant blue. The cardinal tetra is a very popular aquarium fish, but is less widespread than the neon tetra because until recently, it was difficult to breed in captivity.
Pterophyllum is a small genus of freshwater fish from the family Cichlidae known to most aquarists as "Angelfish". All Pterophyllum species originate from the Amazon River , Orinoco River and Essequibo River basins in tropical South America. The three species of Pterophyllum are unusually shaped for cichlids being greatly laterally compressed, with round bodies and elongated triangular dorsal and anal fins. This body shape allows them to hide among roots and plants, often on a vertical surface.

There are dozens of freshwater angelfish varieties. All are the scalare angelfish species ( Pterophyllum scalare ) but have different color patterns and tail lengths. It’s important to note that many may not show their true coloring until they become adults. Something to keep in mind when selecting your young angelfish. Also, because producing unnatural colorings and patterns produces fish that would not survive in the wild and inbreeding may be involved in producing some of these varieties, some freshwater angelfish varieties are inherently less healthy than others.
