The third sign: fish skin
It doesn't matter whether your fish has scales or not. In any case, the skin of the fish is the mirror of its health. Fresh fish has a light and clear skin. This means that the skin of the fish has a mirror-like state. If the skin of the fish is not clear and dull and has a loose and colorless state, be sure that it is not fresh. Don't underestimate this sign. Fourth sign: fish gills The side of the fish's head is located on both sides of its gills. To examine the fish's gills, you must open them by hand. The color of fresh fish gills is red and bloody. If the color of the fish's gills is pale or pale, it is a sign that the fish is old.

6th sign: scales
Check the fish scales. Fresh fish scales are very hard and do not peel off easily.
