It is reserved for animals or plants of different species, but the exact definition is under some discussion. I will use it in its general sense, including obligate the different species need each other and facultative at least one species affects the other species, but the interaction is not essential for either. Used in this sense, symbiosis includes commensalism, mutualism and parasitism.
Emperor shrimp feed on the bypassing substrate and do not harm their sea cucumber host, gaining protection by living on the unpalatable sea cucumber.
Commensalism describes the relationship between two organisms where one organism benefits without affecting the other. Many such examples are found in marine environments.

One likely example is the small porcelain crabs residing on soft corals. The porcelain crabs get a perch to sit on and protection among the arms of the soft coral, while the soft coral is unaffected. Porcelain crab on Dendronephtya soft coral Another example would be the gobies that live on many other animals in the sea, often changing colour to closely resembling their host.
It is likely that the host in most circumstances are rather unaffected by the gobies seeking shelter. They also require at least a low photosynthetic light to allow their bodies to utilize important elements, kind of like how people need sun light to process Vitamin C. When a shrimp molts, it will eat part of its shell to use some of the nutrients its body just lost. Leave the shell in the water. It will be gone before you know it. Like all molting creatures, death is a possibility.
A leg or claw can easily be ripped off, however they usually grow back within 1 or 2 moltings. In a tank with no predators this is fine, but sometimes this can be dangerous if the shrimp cannot swim full speed away from its threat. Tank mates for these animals is fairly simple. Most reef safe fish can live with this guy, as long as shrimp is not in their diet.
Make sure to research what your fish is capable of before putting them in the same tank. The obvious predators would of course be Puffers, sharks, rays, triggers, groupers, lionfish, and any other fish that requires a few crustaceans every once in a while.
Even larger dottybacks can eat a freshly molted shrimp.
Invertebrates are a bit trickier to match up. Crabs are the worst with being friendly, hence the name CRAB! They have no specific diet, and eat whatever and whenever they can.

Keeping snails rather than crabs is more safe. Porcelain crabs or small hermits are also less of a risk. Anemones can eat shrimp, especially the notorious Condylactis which many people are unaware of its hungry nature and lack of symbiosis.
The carpet anemone is also a very dangerous to shrimp species. The shrimp for some reason get drawn to these creatures only to be devoured. These shrimp can live in pairs or by themselves with ample food. They may cannibalize each other if underfed, like all shrimp. These are very fragile, tiny, and easy to lose in a big tank.
