How to feed the Spotted hermit crab?

This invertebrate is an omnivore with carnivorous tendencies. Extremely voracious, it is really not difficult to feed and will accept anything you offer it. For example, mussel or fish flesh, and even dry food will be welcome!

Behavior

Behavior

What kind of behavior does the Spotted hermit crab have?

It is peaceful with everyone, except its fellows, with whom it is very aggressive (even deadly).

Like all hermit crabs, this species must find empty shells available to make their habitat. Make shells of different sizes available to your hermit crab so that it can choose the one that best suits its size. As the hermit crab grows, you will need to offer larger and larger shells.

Cohabitation

Cohabitation

Who can live with the Spotted hermit crab?

Because of its aggressiveness towards other representatives of its species, it is better to maintain only one individual per tank. The presence of two specimens of this species in an aquarium will inevitably result in the death of one of the two crustaceans.

There is predation on corals, anemones, snails and small fish. Cohabitation with all invertebrates that are too small or a little fragile is not recommended, as well as with small fish.

Beware, given its large size, the white-spotted hermit crab can spoil its decor. It must therefore evolve in an environment with solid and very stable elements in order to limit damage. It is therefore incompatible with a reef aquarium with corals. Finally, note that the larger the aquarium, the less the decor will suffer from its movements and appetite!

This invertebrate likes to live in fairly clean water, which will require good filtration. Nevertheless, note that it is very robust and its acclimatization is easy.

He's the biggest hermit crab. The largest specimens can grow up to 10 inches! In fact, its name "megistos" comes from the superlative "mega" which means big.
