When a fish hits a wall, it may not make a sound, but it is definitely feeling the impact. Fish are often seen as creatures that just swim aimlessly in water, but they are actually quite delicate and sensitive to their surroundings. When a fish hits a wall, it can be a traumatic experience that can cause serious injuries.
There are a few things that can happen when a fish hits a wall. The first is that the fish can be stunned or knocked unconscious. This is especially true if the fish hits its head on the wall. The second is that the fish can be injured. The most common injuries are to the fins, but the fish can also break its jaw or spine. The third is that the fish can die. This is most likely to happen if the fish hits its head on the wall and is knocked unconscious.
If you see a fish that has hit a wall, it is important to remove it from the water as soon as possible. This will help to prevent further injury and will also give the fish a chance to recover.
