If you’re wondering what hermit crabs eat and drink, read this. These omnivorous scavengers drink discarded water and shells. They need both saltwater and freshwater to survive. But how do you keep them healthy? Here are some tips for keeping your pet happy. Read on to discover what hermit crabs eat and drink! Listed below are some common foods and beverages they enjoy.

Hermit crabs are omnivorous scavengers
Hermit crabs are omnivorous, meaning they will eat just about anything, including plants. They have two pairs of antennae, one next to the mouth and one behind the body, and use the first pair to taste and feel their prey. Because hermit crabs are nocturnal, they spend most of their day foraging. Hermit crabs are also excellent climbers and will jump on piles to get to food.
While other animals may be active foragers in the wild, hermit crabs have been studied in several contexts, including shell acquisition and feeding. While competing for the same resources might be a major determinant of aggression, research suggests that competition for food resources is a primary cause of aggressive behavior in hermit crabs. Since hermit crabs live in intertidal marine environments, their diets may include high-quality protein-rich carrion. In a study, the crabs were fed mussel and gastropod flesh, which may correlate to potential shell availability.
They eat discarded shells
Hermit crabs eat discarded shell for several reasons. First, these creatures don’t have uniformly hard shells. They are much more closely related to lobsters than to true crabs. They can’t grow their own shells, so they rely on discarded ones from other animals. In their natural habitat, hermit crabs can live in both freshwater and saltwater environments. In captivity, they don’t thrive, but many owners struggle to provide for their pets.
Another reason hermit crabs eat discarded shells is that these animals live in large groups and share the same food source. They also find abandoned shells to tuck into. Hermit crabs live in groups and often form a line to borrow each other’s shell. Then, when one crab leaves its shell, the next one moves into it, creating a cascading effect.
They drink discarded water
Hermit crabs, like all animals, are drawn to water that has been contaminated with plastic. They often live on islands that are surrounded by plastic garbage. These remote islands are sinks for human-made plastic debris, which carries nutrients to the water. Hermit crabs feed on these debris. The trash, which includes food wrappers, plastic bottles, fishing gear, and household trash, begins to decompose when it hits these islands.
Pet hermit crabs spend most of their lives in a sour-smelling terrarium, while wild hermit crabs forage for organic materials and turn them into edible bits. When not buried, hermit crabs will drag around seeds and burrow in the sand during the day to avoid extreme heat. This burrowing action churns the soil, making it more appealing for seedlings.
They need saltwater and freshwater
Hermit crabs need a mixture of saltwater and freshwater. The ratio of the two should be adjusted according to the size of the tank. The sand in the tank should be heated to seventy-five degrees Fahrenheit using an under-tank heater. The humidity should be seventy-five percent to simulate their natural habitat. If you’re not sure how to make saltwater for your hermit crabs, here’s a step-by-step guide.
Generally, hermit crabs can live in either environment, but they do prefer the former. To provide them with saltwater, you can purchase distilled water, or make your own with sea salt. The former is cheaper, but may be riskier. Using marine salt is a good option for hermit crabs because it replicates the salinity of the ocean. The salty water will help aquatic hermit crabs feel at home and adapt quicker.
