I think I have the answer here, but wanted to ask to make sure.\r\n\r\nI ordered two tuxedo urchins online and received them yesterday. Drip acclimated both at the same time over about 1.5-2 hours. One urchin is fine, the other is not. \r\n\r\nThe one that is not fine... I noticed lots of spines (25%) in the shipping bag. Put him in a QT tank with food. Today the poor thing has lost 50-66% of it's spines. This one has not moved much at all.\r\n\r\nTested my water to rule it out:\r\n\r\npH: 8.1 or 8.2; not quite either color really\r\nSG: 1.024\r\nNitrate: 0\r\nNo copper treatment\r\n\r\nI think that is all that is important when it comes to inverts.\r\n\r\nI am thinking the tuxedo is done for and it happened during shipping given the number of spines in the bag. \r\n\r\nThe question is: is there anything I can actually do for it or to I need to send it to the freezer to humanely put it out of it's misery?\r\n\r\nJust wish I could do something for it ... or need to end it fast so it won't suffer more than it already has.
