It is still active. He has been moving around the tank and is still clings to the sides of the rocks. I did wake up this morning to find that one of his legs has decomposed, for lack of a better word. It looks like it has turned to mush and is just hanging on to him by a thread. He looks like he is in bad shape. The funny thing is that I had the water tested before I bought him and Amonnia was 0 nitrite was 0 nitrate was 5ppm PH was 8.2 and my salinaty was 1.022. So my water looks like it was in good shape. How can I tell if it is feeding?
