I finally got a decent picture of these things. Anyone recognize them? The seem to now only be coming off of one crab which is the spiral shell guy. He still will not change out of that shell. However the other guy changed. Still doing daily baths and cleaning the tank.
well he finally changed out of the spiral shell and I took it right out and boiled it. It was a really old damaged shell. And they were hiding deep in and around the spiral. There were holes in it that I could see with a flashlight. Once I boiled the shell they all came floating out. After that only a few more came out with baths and I got rid of then for good.
