Aquatic aliens and the effects of acceleration in space-flight

A sentient species of water-dwelling aliens achieve space-flight.

Their living quarters contain water [no free gases].

They have evolved over millions of years to regulate their buoyancy at will.

Question

Will they be able to withstand much higher acceleration than an air-dweller.

Reason for question

If they maintain neutral buoyancy they won't sink to the bottom and they won't float to the top. Will they merely experience an increase in water-pressure? They are used to dealing with extreme changes in pressure when they dive deep and return to near the surface of their ocean. Therefore surely high acceleration won't inconvenience them.

Notes

If preferred you are at liberty to discuss the difference between turbulent takeoff through an atmosphere or smoother acceleration in a vacuum. I originally intended that the acceleration would only be along the axis of travel.
