As its name implies, this is a large fish that can be kept on a long-term basis only by aquarists who can accommodate it. It is usually available as juveniles of various colors, including (mainly) the wild type and a golden- bodied one. The Red-finned Giant Gourami, which began becoming available in the 1990s, is probably O. Iciticlavus, originally from Sabah, Borneo. The O. septemfasciatus (Sevenstripe Giant Gourami) is only rarely seen. Both these last species were described only during the early 1990s. NOTE: The common name Giant Gourami also applies to Colisa fasciata.
This species has been known in the hobby for more than 100 years. However, unlike the three other members of the genus, it has never been developed into fin or color varieties. The Giant Gourami will interbreed with its closest relatives, C. labiosa (Thick-lipped Gourami) and C. Mia (Dwarf Gourami); the resulting hybrids from C. labiosa crosses are fertile. NOTE: The common name Giant Gourami also applies to Osphronemus gorami.
Gouramis, along with some of their close relatives, such as the Siamese Fighting Fish (Betta splendens) and the Combtail (Belontia signata), have been strong favorites within the hobby for the best part of 100 years. For example, the Dwarf Gourami (Colisa Mia) was first imported into Europe in 1903, while the Paradise Fish (Macropodus opercularis) […]
Osphronemus goramy (Giant gourami) is another fish that is predominantly a food fish as it grows to a large size – 40 cm (16 in) being a good-sized aquarium fish.
The anabantids are a large group of fishes found in the tropical waters of Africa and Asia. They are best known for their ability to breathe atmospheric air. The organ that they use for this is known as the labyrinth (hence the common name labyrinth fishes) and is situated on either side of the head in the gill cavity directly above the gills. The fish takes in air from above the water surface and passes it into two chambers, each of which has a rosette-like structure which looks not unlike a sponge. This has a very good supply of blood vessels close to the surface of the structure, and therefore the fish is able to absorb oxygen from the air.
