Thanks for reaching out and sorry about your fish. Not sure if the cause of death can be identified but changing the tank would be a concern. Were water temperatures, pH, and addition of dechlorinator all checked prior to placing your fish in. Might have come with a disease or parasitic infection. Sorry again.
