Its Dead. When it floats up and the gills are not moving and breathing for sure it is dead
As long as your fish is not upside down all the time, it is not dead. Most likely your fish has a bladder disorder and it cannot help but float upside down.
For some fish, this is a way of escaping predators, for others, such as an upside-down catfish, it allows them to find food (primarily algae) on floating wood.
it might be dead but if its moving tht means its alive and it has swim bladder disease
yes it can affect the fish because if you holed the fish upside down you can cause it not to breathe because all of the water is out of its system
there is no particular reason that your cat fish swims upside down but it could just be the kind of cat fish you have. it isn't abnormal for a cat fish to swim upside down because some can only swim that way.

If your fish is upside down, chances are that it has a swim bladder problem - you should research things to try, but it cannot always be cured.
If your fish cannot swim upright, is swimming on its side or upside down, it most likely has a swim bladder problem.
Gold fish will swim upside down if they have a swim bladder infection, try feeding it fish food that sinks because, when it eats food at the top of the tank it swallows air that goes to it's swim bladder causing it to go upside down at the top or bottom of the tank. Hope I Helped :)
