How long does a fish’s memory last?

The memory ability of fish varies according to species and environment, and different types of fish also have different memory abilities. Some studies have shown that some fish have strong memory capabilities and can remember information about their habitat, food sources, and predators.

For example, research has found that Atlantic swordfish can remember all light patterns up to six months old, which is important for them to track food and avoid enemies. In addition, the caudal spinytail has been shown to memorize up to 40 patterns of different colors and shapes.

In addition, some studies have shown that fish can remember things for hours or even days. For example, some fish will remember where food is and return there later to find food. However, because the brain structure of fish is very different from that of mammals, their long-term memory abilities may be relatively weak.

In general, the memory ability of fish is very flexible and adaptable, but the memory ability of fish will also differ in different species and environments.
