Giant Gourami (Osphronemus goramy)

Giant Gouramis are a hardy fish that can handle a variety of water conditions, are easy to keep and are very active with a voracious appetite. However, because of their adult size, they will require a large aquarium. They make an excellent choice for an experienced aquarist with a huge tank and a strong filter, to handle the bioload these fish produce.

These Gouramis need to have large and relatively non-aggressive tank mates. They are worth the time and energy required to keep them as they have great personalities that are not seen in many fish.

You can keep these Gouramis singly or in pairs; groups are possible if you have a large enough aquarium. However, males are territorial, will tussle amongst themselves, and become aggressive when breeding.

The Giant Gourami is sideways compressed with a deep oval-shaped body and a blunt head. As juveniles, their heads are flat and pointed, but as they mature, they acquire a nuchal hump which is a swollen lump or knob on the forehead, along with a thick chin and thick lips.

Juveniles have a golden yellow body with yellow fins and display 8 to 10 dark bars. The bars vary from a silvery-grey to bluish-black, giving them a striped appearance. However, their colour fades as they develop and they become rather dull and plain, usually with a brownish-black or even an overall pinkish to white colouration.

The Giant Gourami likes to have areas to hide in which can be provided with bogwood and a few rock structures. Providing plants along the sides and back of the aquarium also benefit these Gouramis.

Feeding

In the home aquarium, the Giant 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

Distinguishing male from female Giant Gouramis is relatively straightforward. The males have longer, more pointed anal and dorsal fins and will also develop a larger nuchal hump on the forehead. In contrast, the females anal and dorsal fins will be rounder, and they typically have thicker lips than males.
