Common Myths

Hermit crabs are often misunderstood, leading to improper care and short lifespans. Many myths have contributed to the idea that they are low-maintenance pets, but in reality, they require a well-maintained habitat and proper nutrition to thrive. Below are some of the most common misconceptions about hermit crabs—along with the truth behind them. 

1. Myth: Hermit crabs only need a small plastic tank

 Truth: Hermit crabs need at least a 10-gallon glass tank with proper heating and humidity, not tiny plastic enclosures.

2. Myth: Painted shells are safe and fun for crabs

 Truth: Painted shells are often toxic and can flake off, harming crabs if ingested. Always provide natural, unpainted shells.

3. Myth: Hermit crabs don’t need humidity

 Truth: They breathe through modified gills, which require 70-80% humidity to function. Without it, they slowly suffocate.

4. Myth: Tap water is fine for hermit crabs

 Truth: Tap water contains chlorine and harmful chemicals that can be fatal. Always use dechlorinated fresh and saltwater.

5. Myth: Hermit crabs can survive on commercial pellets alone

 Truth: A balanced diet includes fresh fruits, vegetables, proteins, and calcium sources like cuttlebone—not just pellets.

6. Myth: Hermit crabs only live a few months

 Truth: With proper care, hermit crabs can live 10-30 years—they only die young due to improper conditions.

7. Myth: Molting crabs are dead

 Truth: Molting crabs bury themselves for weeks or months to shed their exoskeleton. Disturbing them can be fatal.

8. Myth: Hermit crabs are solitary animals

 Truth: They are highly social and should always be kept in groups of at least two or more.

By understanding these myths and the real needs of hermit crabs, you can help ensure they live long, healthy lives.
