The diet of Torquigener florealis consists primarily of small invertebrates, including crustaceans, mollusks, and worms.

Torquigener florealis is native to the warm coastal waters of the Indo-Pacific, often inhabiting sandy or muddy substrates near coral reefs.

It thrives in areas with ample hiding spots and access to food resources, such as seagrass beds and reef margins.

The species name may allude to patterns or behaviors associated with courtship displays, specifically the "sand circles" males create that resemble floral designs.

Male fish create large, intricate circular patterns in sandy substrates, which serve as nests to attract females.

These "sand circles" can measure up to 2 meters in diameter and are often adorned with fine textures and ridges to display the male’s skill.

Due to the presence of tetrodotoxin, a potent neurotoxin, this species is not generally consumed and poses risks if improperly prepared.
