I have recently gotten a green galaxea coral and has been in my aquarium for all of a month now and upon close observation i have noticed a clear bodied crustecian that looks like a small shrimp about as long as a fingernail it's eyes have the same milky white tips as the coral does and is hiding in it by having those characteristics. the coral is doing fine and there is no damage done to it. My point being is that is this shrimp like creature good or bad? any answers would be greatly appreciated sorry no pics.
