From a local paper:
A pet fish has been blamed for starting a house fire.
Kipper, an 8-inch catfish in Poole, England, apparently got into a fight with another fish and splashed water onto a nearby electric plug, sending a power surge up the tank's light cable. That burned and melted the tank's plastic lid, which dripped onto a leather couch and set it ablaze.
The fire spread quickly, and Kipper and five other fish were killed. The humans safely fled.
