As much as it shames me to admit it, this time I did not quarantine. I have not seen any feces, however, I have not seen feces from any of them. Unlike my old blue hippo tang who ... lets not get into that. I've only had the pearl almost a week Tuesday April 19th. He still seems very active, and he's no longer hiding. He swims alongside the Yellow Tang and Copperband, both who are slightly larger. I also have one pretty well behaved Striped Damsel, two False Perculas, an Engineer Goby, and two Catalina Gobies. Couple of cleaner shrimp, 4 peppermints. That's it - 180 gallons
