Clownfish dead when I got home :(

[death-by-reef]

I just got home from school and when I got home I check on my reef and one of my clowns was dead. My other fish is a ok and swimming happily. The tank looks great and all of the corals are happy so I don’t thinks it’s a water problem, any ideas? The store I bought it from (@Tiki Corals) has a 7 day DOA policy so I can get a new one free but it’s still sad:(

It's always sad to lose a fish (I lost one today). Sometimes there's just no reason. Could be stress from shipping was a cause.
