Is it possible?

[Baker]

So I was feed the fish some brine today and I also feed the cleaner shrimp as well. This time when I fed the shrimp, I watched it carry all the brine over to the torch coral and feed it. So my question is, is it possible for a cleaner shrimp to have a symbiotic relationship with a coral such as a torch? I thought they just cleaned fish. It seems as through they are a caretaker of all.
