Fishes do not exactly float, except when they die. Although fishes can move upwards and downwards by rising and sinking, sort of like a helium filled balloon. To do this, fishes need to reduce its overall density by reducing its volume without increasing its mass. For this, fishes have what we call a 'swim bladder'. This an organ that expands and contracts, just like a human lung. When the bladder is inflated, the fish has a maximum volume and is pushed to the surface. When its deflated, it has a minimum volume and sinks. In this way, fishes are capable of rising and sinking and also staying at a particular level.
Hope this helped :)

What makes bony fish float?

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.

yes since when their around enemies they pucker up so when their enemies kill them they pucker up and float
Why do blob fish float above the ocean ground?
The flesh of the blobfish is primarily a gelatinous mass with a density slightly less than water; this allows the fish to float above the sea floor without expending energy on swimming.

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.
What is the swim bladder in a fish?

What makes balloons float when they are full of air but not float when they are deflated?
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
