(more) Simon LEE The Giant Red Tail Gourami, one of only three species in this genus, is definitely the most attractive of these very large fish!Giant Red Tail Gourami Contents The Giant Red Tailed Gourami is a slightly smaller, more colorful version of its cousin, the true Giant Gourami, Osphronemus gouramy. This large fish is a relatively new addition to the aquarium hobby. More colorful than its close relative the Giant Gourami, this species natural color can be quite beautiful. It has wonderful blue-green highlights and fins that are trimmed in red. With a maximum size of near to 20 inches, keepers of this fish should plan on eventually having a 100 gallon or larger tank available to house them in. Many fish that are red or partially red are considered to be good luck by many Chinese so the demand for this red finned giant is very high! For more Information on keeping this fish see: |

Habitat: Distribution / Background
Giant Red Tail Gourami are from southeastern Asia, found in Northern Borneo. This impressive fish was first described by Roberts in 1992. These fish are not endangered.
- Scientific Name: Osphronemus laticlavius
- Social Grouping: Solitary - Best kept in a species aquarium or with other large fish that it has been raised with to minimuze aggression.
- IUCN Red List: NE - Not Evaluated or not listed
The Giant Red Tail Gourami has a compressed, oval shaped body and a blunt head. More colorful than its close relative the Giant Gourami, this species natural color can be quite beautiful. It has wonderful blue-green highlights and fins that are trimmed in red. Mature males will develop a 'nuchal hump', a swollen knob or lump on the forehead
Like all other gouramis they can breath air, generally gulping it at the water's surface. They have a special 'labyrinth organ' which acts like a lung which enables them to survive in oxygen-depleted waters.
- Maximum Size: 20.0 inches (50.80 cm)
They are hardy fish, but they grow large, so as adults they will need a very large aquarium. They will eat almost any freshwater aquarium foods if it is trained to do so at an early age. If they are mainly fed live fish, your food bills will be very high so it is suggested that you start to train them on the dried foods as soon as they are obtained.
- Aquarium Hardiness: Moderately hardy
- Aquarist Experience Level: Expert - Although this fish is moderately hardy, the special requirements of such a large species disqualify it for care by all but the most researched and committed of aquarists.
Since they are omnivores, the Giant Red Tail Gourami will generally eat all kinds of foods. Although it can be a voracious predator, this fish will eat almost any freshwater aquarium foods if it is trained to do so at an early age. If they are mainly fed live fish, your food bills will be very high so it is suggested that you start to train them on the dried foods as soon as they are obtained.
Sometimes, predatory fish that are never fed any live fish will grow up not knowing that other fish should be considered dinner. There are reports of large sized Giant Gouramis living peacefully with small tetras or danios.
These fish grow large so as adults they will need a very large aquarium, 100 gallons or larger is recommended. You will also want to be sure to have a good filtration system and do large weekly water changes, with 25% or more being reasonable. As they are large and active, they will need minimal tank decorations.

- Flake Food: Yes
- Tablet Pellet: Yes
- Live foods (fishes, shrimps, worms): Some of Diet

The Giant Red Tail Gourami are generally a peaceful fish, but there can be exceptions to this rule. Occasionally a large male can become very territorial and will attack other fish in their tank. It is best if you plan which species you want in your tank from the very start and obtain them all at or near the same time. Most of the time, fish that are generally considered compatible will get along better if they are raised together.
- Temperament: Semi-aggressive - Although generally a peaceful species, they have a tendency to be territorial and are are not reliably gentle with more delicate tankmates.
- Compatible with:
- Same species - conspecifics: Sometimes
- Peaceful fish (): Threat
- Semi-Aggressive: (): Threat
- Slow Swimmers & Eaters: (): Safe
The Giant Red Tail Gourami males are much more colorful than the females.
The Giant Red Tail Gourami have not yet been bred in captivity. Like most fish in this family, the gourami are bubble nest builders. Their close relative, the Giant Gourami male, will build a ball-shaped nest out of bits of plants just below the surface of the water. Their eggs as well as the fry, are lighter than water and float to the top. See the description of how to breed labyrinth fish in Breeding Freshwater Fish.
- Ease of Propagation: Unknown
The Giant Red Tail Gourami are relatively rare. Specimens will be about $40.00 USD and up.
There is a high demand for this fish in parts of Asia and this helps to keep the price high. Their close relative, Giant Gourami, is commercially produced in many parts of tropical Asia so it is hoped that someone there will soon be able to spawn the Giant Red Tailed Gourami.
