 This study investigated the sensitivity of four anxiety-like behavior paradigms in zebrafish. The results indicated that the novel tank dive test was the most sensitive, followed by the shoaling test, while the light, dark test and shoaling plus novel object test were the least sensitive. Additionally, the study found no correlation between the anxiety-like behaviors and locomotor behaviors such as swimming velocity or immobility.
