Do seahorses self impregnate?

Male Seahorses Get Pregnant and Give Birth

When the swim bladder expands it will increase in volume and therefore displace more water. This increases the fish’s buoyancy and it will float upward. When the swim bladder deflates the fish’s buoyancy decreases and it will sink as it displaces less water.

Why do fish go upside down but still alive?
