Cherry Spider Crab 4cm

The Cherry Spider Crab is a unique and fascinating invertebrate that brings something completely different to the aquarium. Known for its long delicate legs and striking red to cherry colouration, this species is best suited to aquarists looking for an unusual display animal rather than a traditional community tank inhabitant.

This crab displays a vibrant red to deep cherry body colour with long slender legs that extend outward in a spider-like form, giving it its common name. The body itself is relatively small compared to the leg span, and under aquarium lighting the red tones can appear even more intense. Their movement is slow and deliberate, often climbing across surfaces and décor rather than actively swimming. Because of their structure and behaviour, they are often best appreciated in species-focused or carefully planned setups.

Sexing is difficult, and breeding in captivity is uncommon due to the specialised conditions required. In the wild, they are typically found in environments where they can climb and scavenge for food.

Tank Recommendations for your Cherry Spider Crab

A specialised aquarium of 60 litres or larger is recommended depending on the setup. These crabs require structures to climb such as rockwork or driftwood, along with a secure lid as they are capable escape artists.

Suitable Tank Buddies

This species should be kept with great care when considering tank mates.

Usually Compatible

Best kept in species-only setups or with very slow-moving, non-aggressive tank mates.

Sometimes Compatible

Larger non-aggressive fish that will not harass the crab, though there is always some level of risk.

Rarely Compatible

Small fish, shrimp or slow-moving species, as the crab may attempt to catch or injure tank mates.

Feeding your Cherry Spider Crab

These crabs are opportunistic scavengers and will accept a wide range of foods. The ideal diet would be sinking pellets, algae wafers and small pieces of seafood such as prawn or fish, ensuring a varied diet for proper long-term health.
