My red rili shrimp has been doing the same fanning since she last molted. From all the googling and researching I've done, I think it is her trying to spread her pheromones to males because she is ready to breed, but I don't have any males for her to breed with! She also does it more excessively when she eats haha, maybe it is her being excited about food! I also do not think it is parasites, as my red rili that does it looks and acts perfectly healthy and normal otherwise.
