Here's why:
* Space to Roam: Hermit crabs are active creatures that need space to explore and climb. A 1-gallon tank is cramped and restrictive.
* Proper Humidity: Hermit crabs require a specific humidity level for their health. A small tank makes it difficult to maintain the right humidity.
* Temperature Regulation: Hermit crabs need a stable temperature range. A small tank is prone to temperature fluctuations, especially if it's not properly heated.
* Stress: Living in such a small space can cause stress and illness in hermit crabs.
Recommended Tank Size:
A minimum of a 10-gallon tank is recommended for one hermit crab. For multiple crabs, you'll need a larger tank, with a minimum of 5 gallons per crab.
Remember: A larger tank is always better than a smaller one!
