Character and suggestions regarding care

Although it’s a peaceful fish which lives in groups, it is not recommended for home aquariums due to it’s size.

Gold Trevally can grow up to 110 cm what is approximately 43 inches. So 1 specimen requires at least 13200cm² of water surface which is approximately 2046 square inch. This fish should be kept in aquariums that are very large. (e) Medium aquariums have at least 113 Litres (30 US Gallons). Large aquariums have at least 265 Litres (70 US Gallons). Capacity of very large aquariums is at least 700 Litres (185 US Gallons).

It is not very difficult to keep the Gold Trevally fish. (e) The specific gravity (SG) should be between 1,020 and 1,025, the temperature between 23°C (73.4°F) and 26°C (78.8°F). The pH levels shouldn't be outside of 8.0 - 8.3 since most marine fish are used to the mentioned range of pH values.

Suitable for tanks when they are juveniles only, later they are too large to be kept in home tanks. But they have no special requires. They even don’t need hiding places and will eat aquarium food. Even though I would not recommend this fish for aquarium.
