I have noticed that whenever I ship in new specimens of leopard wrasses there is an extremely high mortality rate. I have six healthy established specimens in my system. I was wondering if anybody has any experience with possibly pretreating these fish for internal parasites or any tricks to ensure a higher survival rate. It seems to only happen to the Leopards. I also have the fish shipped with some sand to ease there stress level. Sometimes they will swim in my tank for a day or two and then lay over on there side and die! This has been consistent with the black,ornate,half divided and standard leopard wrasse although I have estbalished specimens from each in my tank!
