Sea Goldie (Pseudanthias squamipinnis)


The Sea Goldie, scientifically known as Pseudanthias squamipinnis, is a vibrant marine fish that belongs to the Sea Basses family. It is native to the Indo-West Pacific region, where it inhabits coral reefs and reef slopes in large schools. Thanks to its striking colors and dynamic behavior, it is a popular choice among marine aquarium enthusiasts.

Care and Behavior


Despite its delicate appearance, the Sea Goldie is considered a semi-aggressive to aggressive species, particularly when kept in small groups or confined spaces. Males can become territorial, especially when competing for dominance or access to females. To reduce aggression, it is advisable to keep this species in small harems with one male and several females in a spacious tank.

Sea Goldies can reach up to 15 cm (approximately 5 inches) in length. A single specimen requires at least 1800 cm² (about 279 square inches) of water surface area. A medium-sized aquarium of at least 113 litres (30 US gallons) is the bare minimum, but larger tanks—especially those above 265 litres (70 US gallons)—are highly recommended for optimal health and social dynamics. Very large aquariums of 700 litres (185 US gallons) or more provide the best environment for groups.

Sea Goldies are relatively easy to care for, making them suitable for aquarists with some prior experience in saltwater setups. They require stable water parameters to thrive. The specific gravity (SG) should be maintained between 1.020 and 1.025. The ideal temperature range is 23°C to 26°C (73.4°F to 78.8°F), and the pH should stay between 8.0 and 8.3, which aligns with typical conditions found in marine environments.

Diet and Feeding


The Sea Goldie is primarily a carnivore but will also consume algae as part of a varied diet. In the wild, it feeds on plankton and small invertebrates. In captivity, it accepts finely chopped meaty foods such as mysis shrimp, brine shrimp, and marine pellets. To maintain health and coloration, it's beneficial to offer small, frequent feedings throughout the day rather than a single large portion. Their active lifestyle and high metabolism require consistent nutrition.
