Mine too...as well as others.
Here is some food for thought:
The barometric pressure increases the further down the water table you go. By this I mean that the pressure at the surface is less than the pressure at say...10 feet.
Fish use their swim bladder to regulate the ability to suspend. They can move gas from the blood system to the bladder to rise and reverse the process to descend. The exchange rate (unknown to me) is different for each species...and this rate is unaffected by water pressure and temperature.
