Normally, an upside-down fish in your tank is bad news

What does it mean when fish turn upside down?
That said, the decomposition process can sometimes result in enough gas being produced and trapped inside the fish to cause it to float to the surface. So in short,

Can dead fish sink?
Most fish are slightly denser than water, so sink immediately after death

What are sharks afraid of?
Why do Stingrays fall asleep when upside down?
Causes of
Tonic Immobility
When they're upside down, their dorsal fins become straighter and more streamlined. The atypical stance is believed to have an effect on reciprocity with their surroundings, both through their motor and sensory reactions. Some believe tonic immobility might be a defense mechanism for sharks.

Why is my fish twirling?
