Poorly Pincushion

[stef_uk]

After a few days of not seeing my Pincushion Urchin,which was nothing strange,i did a search for him today and found him wedged firmly between my eggcrate and rock. Had to move a load of rock to get to him and slowly nudge him out.
As i moved him i saw that he had dropped loads of spines and has what looks like dead tissue where he was pressed against the eggcrate.I've gently and slowly moved him to the front of the tank where i can see him and fastened red and green seaweed nearby to try and get him to eat.
He looks in bad shape and im not sure he'll last..Should i leave him where he is and cross my fingers or set up my BiOrb as a hospital tank for him?

Not sure what to do for the best really...any opinions would be great.

I seem to recall reading that urchins drop their spines at times of stress - so maybe it was because he was trapped but you should also test your water to ensure there is nothing wrong there as well
