Red Devil Crab

Why Red Devil Crabs Make Great Pets?

Their bold colors and intriguing behaviors make them a living piece of art.

Require a small semi-aquatic tank with minimal upkeep.

Feed on a simple diet of pellets, vegetables, and occasional protein.

A small tank (10–20 gallons) is sufficient, making them perfect for apartments or limited spaces.

They are active during the day, digging burrows, exploring their environment, and sometimes engaging in light territorial displays.

Unlike traditional pets, they don’t make noise and won’t disturb your household.

Observing them teaches children about ecosystems, responsibility, and aquatic-terrestrial animal care.

With proper care, they can live up to 3–5 years.

Semi-Aquatic Nature: While they are commonly kept in aquariums, Red Devil Crabs require both land and water to mimic their natural habitat.

Behavior: These crabs are terrestrial for most of their activities, such as burrowing and exploring, but they occasionally enter water for hydration and feeding.

Tank Size

A minimum of 10 gallons for 2–3 crabs is recommended.

Larger tanks (20 gallons or more) are ideal for groups, as Red Devil Crabs are mildly territorial.

Substrate and Décor

Substrate: Use coconut fiber, sand, or fine gravel for burrowing.

Décor: Add driftwood, rocks, live plants, and hiding spots like caves or small terracotta pots. These mimic their natural habitat and reduce stress.

Species compatibility

Avoid fish or invertebrates that could harm or be harmed by the crab.

Suitable companions include small, peaceful species like snails or shrimp.
