The Arothron spp. (Citrinellus) is a large pufferfish species prized for its distinctive shape and engaging personality. Due to their size and temperament, they are best suited to experienced hobbyists with ample aquarium space.
Care Level: Moderate to advanced care is recommended. These puffers require stable water parameters and a well-maintained environment.
Temperament and Compatibility: Arothron puffers can be territorial and may nip at smaller or slow-moving tankmates. They are best kept with robust, non-aggressive species. Avoid housing with delicate or very small fish.
Diet: Carnivorous by nature, they thrive on a varied diet including hard-shelled foods such as molluscs, crustaceans, and specialised frozen or prepared puffer diets to help wear down their continuously growing teeth.
Tank Requirements: A minimum tank size of 250 litres is advised to accommodate their active swimming and territorial behaviour. Provide plenty of hiding places and open swimming areas.
Reef Compatibility: With Caution. They may nip at corals or invertebrates, so careful monitoring is essential if kept in reef systems.
Water Parameters: Maintain stable marine conditions with temperature between 24-27°C, salinity at 1.020-1.025 SG, and good water quality with regular maintenance.
Origin and Size: Origin details are not provided. These puffers can reach a large size, so plan accordingly.
