# Is there a relation between the pressure at a point in a fluid and the pressure on the surface of a horizontal object placed at the same point? [duplicate]

So if the pressure in a large fish tank 10 meters below water surface is 50 Glitches (didn't have a realistic number so I put an unrealistic unit), and a Pancake batfish stands still there for a while, does it experience pressure equal to 50 Glitches? , The answer should be yes; by looking at the derivation of the formula $$P=\rho gh$$

This question was an alternate question to whether the Pressure on an object midway in a fluid depends on the area of the object or not, and the answer is No if I'm correct, but I also think that the pressure on the object depends on the area of the container, in other words if the batfish stand still for some more time and walls keep pushing towards it it will feel more pressure, but can't see the formula above saying anything about it, the derivation does though. What do you think?

Pressure in water at atmospheric condition isn't dependent on volume but depth (it's evident in the formula $$P=\rho gh$$ where h is depth), but when you squeeze the tank in on the fish, the water height increases and if the fish still remains at the bottom, the pressure on the fish surely increase at that depth. And it's the force that's proportional to area not pressure: $$F=PA$$
