General Description:
The Threespot Dascyllus, scientifically known as Dascyllus trimaculatus, belongs to the Pomacentridae family. It is characterized by its less colorful appearance compared to Chromis and its slightly higher level of aggressiveness towards other species, especially in terms of territorial behavior.
Aquarium Suitability:
Threespot Dascyllus are generally suitable for most aquarium setups but can exhibit aggressive tendencies towards other fish, particularly when it comes to defending their territory. They can be kept in shoals if provided with ample space and stony corals with branches for hiding.
Demands:
These fish have a hardy nature and can adapt well to aquarium environments. They thrive in water conditions with a pH range of 8.1-8.4, a temperature between 22.2-25.6°C, and a specific gravity of 1.020-1.025. They prefer a carbonate hardness (KH) of 8-12.
Care and Hardiness:
Threespot Dascyllus are known for their aggressive behavior towards most approaching fishes, emphasizing the need for ample space and appropriate hiding spots in the aquarium. They are generally hardy fish that can withstand fluctuations in water parameters.
Reef Suitability:
Threespot Dascyllus are considered reef-safe, making them a suitable addition to reef aquariums. However, their territorial nature and potential aggression towards other tank mates should be carefully monitored in a reef setting.
Aquarium Setup:
For Threespot Dascyllus, it is essential to provide a tank with a minimum size of 200 liters. The aquarium should have ample live rocks with hiding places for the fish to retreat to. Maintaining a stable pH, temperature, and salinity level is crucial for their well-being.
Behaviour:
These fish exhibit territorial behavior and can be aggressive towards other species, especially when it comes to defending their territory. They are known to form shoals but may display aggression towards each other, particularly in small groups.
Feeding and Diet:
Threespot Dascyllus primarily feed on microalgae, small crustaceans like krill and mysis, and zooplankton such as Cyclops and pods. Offering a varied diet rich in nutrients is essential for their overall health and vitality.
Habitat and Distribution:
Threespot Dascyllus are found in the Indo-Pacific region, ranging from the Red Sea and East Africa to southern Japan and Sydney, Australia. They prefer habitats with stony corals and branching structures where they can establish their territory and find hiding spots.
