Are tank fish afraid of sound?

Some tank fish may exhibit startle responses or other signs of discomfort when exposed to loud or sudden sounds, but others may remain unaffected. The response of a fish to sound can vary depending on several factors, including the species, previous experiences, and overall sensitivity to sensory stimuli. The response can also differ based on the characteristics of the sound, such as its frequency, volume, and pattern.

While tank fish in general aren't necessarily "afraid" of sound the way humans and other mammals might be, it's essential to create a harmonious and stress-free environment for their well-being. Sudden and excessive noise can cause disturbance or disruption and potentially lead to undue stress, behavioral changes, or physiological responses as fish have sensitive hearing organs
