Callistoctopus macropus is a striking species of octopus known for its distinctive long arms and nocturnal behaviour. This cephalopod is a captivating addition to mature marine aquariums, offering both intrigue and natural beauty.
Care Level: This species requires an advanced level of care due to its specialised needs and sensitivity to water quality. It is recommended for experienced marine aquarists only.
Feeding: Callistoctopus macropus is carnivorous and thrives on a diet of live or frozen meaty foods such as shrimp, crabs, small fish, and molluscs. Feeding should be done daily or every other day to maintain health.
Compatibility and Reef Safety: This octopus is generally solitary and may prey on tank mates, so it is best housed in a species-specific setup or with robust, non-prey species. It is not reef safe as it may attack invertebrates and fish.
Tank Requirements: A minimum tank size of 150 litres is recommended to provide sufficient space and hiding places. The aquarium should have a secure lid to prevent escape, as octopuses are known escape artists.
Water Parameters: Stable marine conditions with a temperature range of 22-26°C, salinity of 1.023-1.025 SG, and excellent water quality are essential. Moderate water flow is preferred to mimic natural habitats.
Placement: Provide plenty of rockwork, caves, and crevices for shelter and exploration. Dim lighting is beneficial as this species is nocturnal and prefers low light conditions.
Overall, Callistoctopus macropus is a rewarding but demanding species that requires careful husbandry and a dedicated setup to thrive in captivity.
