I have been putting food near him in case he got better, but every time jumping jacks would just walk by and eat it. Today Salty grabbed him! There was nothing to grab on that was stable and since salty is so big jumping jacks was just wiggling and writhing. I moved the two of them into the glass mug I have on top of the driftwood (to hold it down) Salty grabbed the edge and now is holding on to the wall. He hasn't moved on his own, beyond the grabing on the wall. Regardless that's a definite improvement.
