The cleaner shrimp is not just a cleanup crew for your tank but for your fish as well. They support fish health by removing parasites and dead tissue adding a ton of personality to any tank.
Cleaner Shrimp
Cleaner shrimp are so called because they exhibit a cleaning symbiosis with client fish where the shrimp clean parasites from the fish. The fish benefit by having parasites removed from them, and the shrimp gain the nutritional value of the parasites. The shrimp also eat the mucus and parasites around the wounds of injured fish, which reduces infections and helps healing. The action of cleansing further aids the health of client fish by reducing their stress levels.[2][3] In many coral reefs, cleaner shrimp congregate at cleaning stations. In this behaviour cleaner shrimps are similar to cleaner fish, and sometimes may join with cleaner wrasse and other cleaner fish attending to client fish.
