General Description
Chromis dimidiata, commonly known as Chocolatedip Chromis or Two-tone Puller, is a member of the Pomacentridae family. These fish are recognized for their shiny blue and green color nuances and are often found in large shoals, although they may become less social as they mature, displaying increased aggression towards each other.
Aquarium Suitability
The Chocolatedip Chromis is suitable for most aquarium setups, preferably in pairs or shoals. However, in a small shoal, aggression may be directed towards individual specimens but can diminish over time. They are known to be hardy fish but require frequent feeding and good hiding places in the aquarium, typically between live rocks. These fish prefer a varied diet consisting of microalgae, small crustaceans, and zooplankton.
Demands
This species requires a minimum tank size of 300 liters and can reach a maximum size of 9.0cm. They are generally hardy but are sensitive during transportation and acclimatization. When maintained in a shoal, it is recommended to have one male to five or more females to minimize aggression within the group.
Aquarium Setup
It is essential to provide hiding places within the aquarium, such as live rocks, to accommodate the Chocolatedip Chromis' natural behavior. Maintaining the water conditions within the parameters of kh: 8-12, ph: 8.1-8.4, sg: 1.020-1.025, and a temperature range of 22.2-25.6°C is crucial for their well-being.
Behaviour
These fish tend to swim in shoals, especially when first introduced into the tank, but may become aggressive towards each other over time. They should be observed for any signs of aggression, especially in smaller groups.
Feeding and Diet
The Chocolatedip Chromis must be fed a varied diet that includes microalgae (e.g., spirulina), small crustaceans (krill, mysis, artemia), and zooplankton (Cyclops, pods). Frequent feeding, especially during the initial stages, is necessary for their health and vitality.
Reef Suitability
These fish are deemed reef-safe and can thrive in reef aquarium setups. Ensuring there are no similarly aggressive species present can help maintain harmony within the tank.
Habitat and Distribution
Chromis dimidiata is native to the Red Sea in the Western Indian Ocean region. These fish are often found in coral reefs and live on zooplankton, displaying an affinity for hiding in stony corals like Acropora.
