They aren't really. Floating is when an object is held up against the pull of gravity due to the density of the liquid in which the object is resting (though technically, while sitting in a chair you are "floating" but we generally don't use the word that way). Sinking is just an object being pulled down by gravity despite the resistance of the liquid. Sinking is functionally the same as falling, however it generally happens at a slower rate due to the higher resistance (friction) provided by liquid over gasses.
When it's floating perfectly still, neither sinking nor floating upwards.
Certainly! A catchy title that involves sinking and floating could be "The Science of Buoyancy: Navigating Sinking and Floating." This title effectively captures the concept of buoyancy and the contrasting states of sinking and floating in a clear and engaging manner.
The opposite of floating would be sinking.
The weight of an object is determined by its mass. Objects with greater mass will sink in a fluid with a greater tendency than objects with lesser mass. Buoyant forces from a fluid exert an upward force on objects, and if the buoyant force is greater than the gravitational force, the object will float.
Fish do not normally "float around" they swim. If your fish is floating/sinking then it is probably dead.

The weight of the water (or other liquid, or gas) displaced is equal to the force with which the water will push the object upwards.
Breathe while floating. Hold it while sunk.

Floating occurs when an object is less dense than the fluid it is placed in, causing it to stay on the surface of the fluid rather than sinking. This can happen when the buoyant force acting upward on the object is greater than the gravitational force acting downward.
Buoyancy is not a force, but rather a phenomenon that results from the interaction of an object with a fluid, such as water or air. It is the upward force exerted by a fluid that opposes the weight of an object immersed in it. In equilibrium, the buoyant force is equal to the weight of the displaced fluid, leading to the object floating or sinking.
