Dardanus spp.

Datasheet

General Description

The Hermit Crab with Anemone, specifically belonging to the Dardanus spp., establishes a symbiotic relationship with the anemone Calliactis polypus, aiding each other in camouflage, protection, and food sharing. Three specific species - D. pedunculatus, D. tinctor, and D. deformis - showcase this fascinating behavior in their natural habitat.

Aquarium Suitability

While generally considered easy to care for, this Hermit Crab can become aggressive, making it unsuitable for peaceful fish or reef aquariums due to its tendency to consume fish, snails, and worms. It thrives in environments with abundant stable rock work and dim lighting. Multiple sizes of gastropod shells should be provided for the crab to swap into as it grows.

Care and Hardiness

The Hermit Crab with Anemone is an omnivore, requiring a diet consisting of detritus, algae, dried seaweed, mollusks, worms, and other meaty items. Regular supplementation of calcium, magnesium, iodine, and trace elements is necessary to maintain its health. It can reach a maximum size of 10.2cm and prefers water conditions with a KH of 8-12, pH of 8.1-8.4, and specific gravity of 1.023-1.025.

Reef Suitability

This species is deemed unsuitable for reef environments due to its aggressive nature and tendency to prey on smaller organisms typically found in reef tanks.

Aquarium Setup

To cater to the Hermit Crab's needs, an aquarium with ample stable rock formations and subdued lighting is recommended. The setup should include various sizes of gastropod shells for the crab to inhabit as it grows, along with suitable hiding spots and open areas for movement.

Behaviour

Known for its aggressive temperament, the Hermit Crab with Anemone should be housed in a species-specific aquarium or with appropriate tank mates that can withstand its predatory behavior.

Feeding and Diet

Being an omnivorous species, this crab requires a varied diet consisting of detritus, algae, dried seaweed, mollusks, worms, and other meaty foods. Regular provision of these food items is crucial for its health and vitality.
