I ordered a Hummelincki from reef scavengers a couple days ago. It arrived yesterday dead. Its mantle was about 1 1/4 inches and arm span of about 5 inches so it was most likely a juvenile. The water was fairly cold however I did not get a chance to record the temperature when it arrived, It felt like it was definitely under 70. the nitrite was 10 and the nitrate was 200. The PH was between 6 and 7. The water was very cloudy and smelly. It was in a bag within a bigger bag in a box. So there were no cold/hot packs in it, nor was there any sort of insulation. Here are the pictures and I should be getting a reshipment as soon as they get another in. Reef Scavengers was very helpful with assessing and treating the situation.
