Earl my urchin has seemed to pass I am so bummed! He took a very large tumble and although he looked like he was getting better, he stopped attaching to the walls and was flipping over. Today he’s dropped all his needles and his little tentacles are no longer coming out. I’m not really holding out hope but I am so upset he’s only survived 2 months and he was a juvenile. There was so much food too and water chemistry hasn’t changed. Should I stick him in the fridge or wait a bit longer? I wanted to give him some time but he’s no longer responding to any stimuli.
