Urchin died

[Erink]

Hey,
Can an urchin die from being over stressed? He was doing awesome, I was supplementing his food with green seaweed. About 4 days ago I checked my water parameters and they were not the greatest. I did a water change but first moved my rocks around. I got everything back to normal then my urchin started acting funny. It seemed he was eating because he was taking the seaweed. I always wait to make sure he doesn't release it. I checked my paparameters again last night and everything is ok, ammonia a wee bit high but I added bacteria and bioballs. I've had him for about 10 months and never had a problem. He even had his own little cave. What happened

Without knowing what your parameters were before and after, it's going to be hard to tell. "Bad, good, high, low" all are relative. Also need things like temperature and salinity to be able to offer up and educated guess
