So my cousin asked me to watch his crayfish for a month because they are moving. He had a small tank for the two that he brought over. The food that i fed them were frozen blocks of bloodworms that made the tank super disgusting. I came home one day and the white crayfish was not moving AT ALL. The tank was disgusting and gross so i was scared he was dead and moved both of them to a separate tank i was preparing for my baby mollies. The white one just lays there amd moves a little bit. He only moved a few steps backwards in about 10 minutes. Is he dying?? The blue one walks around like normal. Help! Is there anything i can do??
