hermit crab
This is a hermit crab from The Pagurittagracilipes from Indonesia. Very small in size, living in the home of Christmas Tree Coral. Their pliers can be seen in the diagram, so safety is not an issue for them. It's uncertain whether they'll eat the Christmas tree and burrow into it or look for the hole in the dead Christmas tree and go through it. They are never picky eaters, and anything that floats over can be eaten. I reckon something like an antenna is used for predation.

When they grow to a certain size, they may have to be invited out of the tank, because there is a possibility of threatening other invertebrates and fish smaller than them.
Electric light crab
Electric light crabs, and they also have a name called spray crabs. They are also a very common crab, the reason is also inseparable from their algae-eating nature, but the electric light crab is an opportunist, if there is meat to eat, they will never eat vegetarian, as long as there is a chance to encounter unguarded small fish, it will definitely become a small dish, so to raise electric light crab must choose a trumpet.
