Freshwater crabs add personality and activity to the right setup, with quirky behavior that makes them a favorite for hobbyists looking for something different. Our collection includes popular freshwater and semi-aquatic species.

• Difficulty: Intermediate (research the specific species before buying)
• Water parameters: pH 7.0 to 8.0, temperature 72 to 82°F, GH 8 to 15 (general guidance; check the care requirements of each species)
• Tank setup: Many freshwater crabs are semi-aquatic and need access to land or a paludarium-style setup with both water and dry areas; a secure lid is essential, as crabs are skilled escape artists
• Note: Care varies significantly by species. Some are fully aquatic, others require land access. Most are opportunistic and may be unsuitable for tanks with small shrimp or slow fish.

Crabs are best for keepers willing to match the habitat to the species. They're active scavengers and add a unique dynamic to a species-appropriate tank. Always confirm the specific species' needs and temperament before adding to a community setup.
