What is the salinity level for a clown fish?

Clownfish, also known as anemonefish, are typically found in tropical marine waters. They have adapted to live in a range of salinities, but they generally prefer a salinity level between 35 and 40 parts per thousand (ppt). This salinity range is similar to that of seawater, which has an average salinity of around 35 ppt. Clownfish can tolerate some fluctuations in salinity, but they may experience stress or health issues if the salinity level deviates too far from their preferred range.
