Whats wrong with your fish if it wont swim or float but its not dead?
Perhaps its in a sort of shock? If the fish in question is a new pet fish, I mean. Normally when you buy a new fish, it comes in a plastic baggie. You're supposed to place the sealed baggy (with fish/water still inside) into its new fish tank. This makes the water in the baggy slowly change to the temperature of the water in the fish tank, and prevents the fish from undergoing the "shock" that accompanies dumping it into a different temperature environment.

Can a non salt water fish be in salt water?
No. A fish's body is naturally buoyant to allow it to float at a certain level in the water. Saltwater is more dense (because of the salt), which makes a fish more buoyant. A freshwater fish, swimming in saltwater, will float too high in the water, and it will die from struggling to keep itself at a deeper water level.
Why does your male betta fish float on its side?
This could be caused by over-feeding. Fish have air bladders and they control how they float in water. If they eat to much this may damage the bladder and in return cause them to float abnormal.
Why are fish not swimming?
Most fish have swim bladders giving them buoyancy that allows them to "float" at various levels in water. While some species are surface dwellers other fish floating on the surface are deceased and float because of gases formed within their bodies due to the process of decay.
Why do fish float in fish tanks?
