Invertebrates
Many crustaceans also perform practical tasks - e.g. Hermit crabs are important part of the "cleaning crew" in the aquarium and eat algae and food remains, cleaner shrimps (Lysmata amboinensis) free fish from parasites such as the pathogens of "Ichthyo" and Wurdemanni shrimp (Lysmata wurdemanni) eat Aiptasia. Other species such as the sexy shrimp (Thor ambionensis) or the anemon crab (Neopetrolisthes maculatus) excite by their appearance and behavior and offer, especially for nano basins and small aquariums, the opportunity to bring more live into the tank.
