Bought this on the last day of my trip to Bulgaria. During the purchase I thought it would just have been found washed ashore. I showed it to a friend who said if I didn't have any documentation, it was probably harvested live and illegally. Can anyone tell me if that is likely and if so, what can I do to compensate for my mistake? Like replanting efforts I can donate to?

I saw this guy at the aquarium of the pacific in Long Beach, CA. He was the only one with this little hairdo. I can’t find anything on the internet about it and none of the pictures online show it either!
