This situation is more common among fish friends. Judging from the picture, the fish has lost its swimming ability and is floating on the water. Although the gills are still closed, its life is coming to an end. There are two reasons for the loss of swim bladder, one is muscle weakness or spasm of fish, and the fish loses its balance, which leads to the loss of swim bladder. The other is abnormal gastrointestinal tract, which causes bacteria to infect swim bladder through intestinal catheter, leading to imbalance of fish. The former can be recovered as long as the stress response is eliminated. The latter is difficult to cure.

I hope the answer can help you, please adopt it.
