Would raising the temperature of a 100 gallon fish tank 5 dgrees kill salt water fish?

the name of the salt water fish is not given. more to the pointy is that gold fish are fresh water fish- therefore salt water fish other than anteroom's or catadromos fishes would eventualy die. These fish die because the salt water is cooler than claen water.

Also, it would depend on what the temperature of the tank was before you changed it.
