Opaline Gourami (Trichopodus trichopterus)

Opaline Gourami is a peaceful, calm, attention-seeking and interesting fish with unique colours.

It is not suitable for housing with small fish because they are likely to eat them. Males can be somewhat aggressive towards one another, so it is essential to keep them in a group to spread the aggression.

This species has a grey-silver body elongated body, which is flattened laterally, the pectoral fins are large and transparent, and the anal fin extends from the chest to the base of the tail. The body displays dark patches of different size and irregular shapes.

The Opaline Gourami is a colour variation of the Blue Gourami.

This Species is a labyrinth fish that has a respiratory organ, allowing them to breathe air.

In the home aquarium, the Opaline 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

The best way to distinguish between the female and the male is the fins.

In the male, the dorsal and anal fin is long and pointed, while the females are shorter and rounded.
