There is a kind of decapod shrimp called clean shrimp, whose occupation is to remove impurities from fish and provide medical services. Clean shrimps not only eat parasites on the skin of big fish, but also get into the mouth of big fish to "brush their teeth" and eliminate the food and parasites left between their teeth. No matter how big the fish is, when invited to "cool off", they will obediently sway in the same place, which is very deferential. If a fish is too sick, it will attract hundreds of clean shrimps to "consult" it at the same time. Thanks to their hard work, fish grow healthier.
Rock shrimp is also a kind of decapod shrimp. Much lazier than clean shrimp. Don't say that you don't do something for other animals, and you don't even have a fixed place to live. It always likes to keep company with those parasitic animals and stay with them. In order to adapt to this parasitic life, rock shrimp has gorgeous spots on its appearance and its body color is also very changeable. Like the gentle seabed rocks in the Mediterranean, anemones are covered, and anemones are natural hiding places for sagittal shrimp and amethyst shrimp. Rock shrimps always snuggle up next to anemones named Pulsatilla, as close as brothers.
