lysmata Debellus (scarlet cleaner, blood shrimp) notcturnal, reclusive, often not visible, some may eat only polyps, such as soft corals, zoanthids and small stony corals. ( keep an eye on this one) if well fed you may not have a problem, but, if your corals show damage or something is bothering them keep an eye on the shrimp. prefers dim lighting. not to worry just keep an eye on it. as usual this information is the standard and may not apply to the animal you have or the one you have could change, whos to say. anyway a beautiful shrimp.
