Giant Red Tail Gourami (Osphronemus laticlavius)

Giant Red Tail Gourami are usually peaceful, but there can be exceptions to this rule, mainly when they are kept in an inadequately sized aquarium. In rare situations, a large male will become territorial and attack other fish, making them unsuitable for the beginner aquarist. Still, in an appropriately sized tank, they are generally a good community fish with other larger species.

When juveniles are raised with smaller fish such as barbs, tetras, and danios, they don’t consider them as dinner and usually ignore them. However, as they grow into adults, they control the tank and any new additions, regardless of size, will more than likely be killed.

Giant Red Tail Gourami are very large and have a sideways tight, deep, oval-shaped body, and a short head. The bodies of Juveniles are a steely blueish-grey to black that develop beautiful blue-green highlights as the fish mature.

In adults, the body colour is blueish-green, almost black; the dorsal and anal fins are elongated, and the pectoral fins and tail are rounded and extensive. The ventral fins are threadlike.

A black eye spot appears at the base of the pectoral fins, and another larger black eyespot appears on the caudal peduncle. Besides having bright red fins and filamentous extensions, the forehead hump is adorned with a hump.

Feeding

In the home aquarium, the Giant Red Tail Gourami will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

It is quite hard to differentiate males from females. However, Usually, the females have thicker lips and are a lot duller in colour than the males.
