Can you keep hermit crabs with other animals in the same habitat?

It depends on the specific species of hermit crabs and the other animals in question. Some hermit crabs can tolerate or even benefit from living with certain other animals, while others may be incompatible. Here are a few general guidelines:

Compatible tankmates for hermit crabs:

- Snails: Many species of snails, such as nerite snails and mystery snails, can live peacefully with hermit crabs. Snails help to clean the tank and can provide additional calcium for the hermit crabs' shells.

- Isopods: Isopods, such as dwarf white isopods and powder blue isopods, are small crustaceans that can help to clean the tank and provide a food source for the hermit crabs.

- Amphipods: Amphipods, such as scuds and hyalella, are small crustaceans that can also help to clean the tank and provide a food source for the hermit crabs.

- Fish: Some species of fish, such as gobies and blennies, can live peacefully with hermit crabs. However, it is important to choose fish that are not aggressive or territorial, as they may harm the hermit crabs.

- Frogs: Some species of frogs, such as poison dart frogs and reed frogs, can live peacefully with hermit crabs. However, it is important to choose frogs that are not too large or aggressive, as they may harm the hermit crabs.

Incompatible tankmates for hermit crabs:

- Crabs: Hermit crabs are territorial and may fight with other crabs, especially if they are of the same species.

- Shrimp: Shrimp are often eaten by hermit crabs.

- Fish: Some species of fish, such as angelfish and bettas, are known to eat hermit crabs.

- Mammals: Mammals, such as cats and dogs, may view hermit crabs as prey.

It is always important to do research on the specific species of hermit crab and other animals you are considering keeping together to ensure that they are compatible.
