Pitho Crab
Pitho Crab (Pitho spp.)
🦀 Compact Algae Assassin – Reef Safe & Low Profile
Meet the Pitho Crab, one of the reef hobby’s most underrated clean-up crew members. With its chunky, rounded shell and stealthy movements, this nocturnal grazer munches on film algae, detritus, and even leftover food—keeping your tank clean without making a scene.
💡 Appearance: Thick-shelled with a mottled dark-to-purple carapace and sturdy claws
🌿 Diet: Film algae, diatoms, detritus, uneaten food
📏 Size: ~2" at full size
💧 Tank Size: Great for nano tanks and up
🧽 Reef Safe: Yes – peaceful and non-aggressive toward corals
🌒 Activity: Mostly nocturnal; hides in rockwork during the day
🔧 Maintenance: Extremely hardy and easy to care for
🧠 Pro Tip: Unlike some crabs, Pithos are not bulldozers—they're excellent for tight reef structures and won't knock over frags.
🔁 Recommended Qty: 1 per 10–15 gallons
