The Red Carnaval Vampire Crab (Geosesarma sp.) is one of the most captivating species of freshwater crabs available to aquarists. Renowned for its vivid red and black coloration and glowing yellow eyes, this crab instantly becomes the focal point of any paludarium setup.

🏝️ Habitat & Tank Setup

These crabs thrive in a paludarium, which provides both land and shallow water areas. A 60% land / 40% water environment is ideal. Use natural substrates like coconut fiber, moss, and driftwood, and include hiding spots to mimic their native tropical forest habitat.

Maintain a stable temperature between 24–28°C and pH around 7.2–8.0. Gentle filtration and frequent water changes are recommended to prevent waste buildup.

🍽️ Diet & Feeding

Red Carnaval Vampire Crabs are omnivorous scavengers. They feed on:

• Sinking shrimp pellets or crab granules

• Blanched vegetables (spinach, zucchini)

• Live or frozen foods (bloodworms, brine shrimp)

Feed them once daily in small portions to maintain water quality.

💡 Behavior & Compatibility

These crabs are territorial but social when kept in small groups (1 male per 2–3 females). Avoid housing them with aggressive fish or large tankmates. They do well with small, peaceful fish or snails in a semi-aquatic setup.

🌿 Breeding

Breeding can occur in captivity under stable conditions. Females carry eggs under their abdomen until hatching. Juvenile crabs are fully formed miniature versions of adults, ready to explore both land and water.

🧰 Care Tips for Beginners

• Ensure secure lids – these crabs can climb!

• Keep humidity high (70–90%) using misting systems.

• Provide both freshwater and dry areas for natural behavior.

• Regularly monitor water parameters for optimal health.

With proper care, the Red Carnaval Vampire Crab will reward you with color, personality, and fascinating behavior that bring life to your aquarium or terrarium.
