Alright One of my Science teachers just recently bought a Blue Spot Sting ray median size, he only had it for a little over a mouth, It died On Thursday during the end the day, between 2 large pieces of live rock. He was alive during the died and he just died out of no where, he seem fine the day before, no change in eating habits or anything.
This was a very strange I thought for it to die all a sudden, the tank was in a class room setting could it be the noise from class and students, that may have stress it out and cause it to have a sudden death?

photos of the aquarium.
also after when this problem have been solve or concluded
any recommendations on a tank occupant, that's hardy and can stand the settings of a classroom that wont get too big for a 180gallon aquarium.
