If you QT, use Prazipro and avoid copper. They don't have scales and are sensitive to medications. Feed Mysis shrimp, live black worms and chopped up squid, clam and fish. Peaceful and often ignored by other fish (though I wouldn't throw one in a tank with triggers, etc.). Should be fed multiple times per day. Due to their body type it can be difficult to tell if they're losing weight/mass. Not the best swimmers in a home aquarium with a lot of flow, so can be victims of anemones and stinging LPS. They have the potential to get pretty big, but I've never seen one in a home aquarium come close to full grown size.
