    1. Because the conditions in the water are so awful for the fish it wants to get somewhere else and jumping is the only thing available to it. Or because something is chasing them and they are trying to get away.

    2. Because fish aren't known for their big brains so do not know there isn't water water everywhere.

    3. Because they do not realize that when they jump out, unless some human finds them fast, they will either be eatened by something, be stepped on by someone, not be able to breath and die, will dry up. Fish don't know beans about their own anatomy. The concept of areas where things live without being surrounded in water doesn't cross their minds.

    4. And I've seen fish jump out of water out of enthusiasm--kind of like a teenager who does those extreme things just because he doesn't think he'll die.

    They jump because they need more space and they think outside have more space because they feel uncomfortable inside because of small space you have a large tank for them or they jump because want to get out because they are chasing, uncomfortable, stressed, etc.

    Fish are known mostly for swimming in water and not jumping out of the water. However, certain fishes tend to jump and some can jump fairly high. Some can even fly. Well not really, but the flying fish can actually soar for quite a distance. Fish tend to jump for several reasons, the most common being because the fish is hunting or is being hunted. Jumping makes for a good defense mechanism as the fish being hunted can temporarily escape the fish that is doing the hunting. Game fish such as marlin and largemouth bass tend to jump out of the water to loosen the hook that may be stuck to their lip. These fish will jump clear out of the water and shake their head violently in an effort to remove the hook that is impeding their freedom. Other fish, such as the invasive Asian carp, have been known to jump out of the water when an outboard powered boat drives through the water in which these fish live. There are plenty of YouTube videos showing these carp jumping out of the water, often landing in the boats that are going through the area. It is not known why these fish jump but there is speculation that the outboard motor's noise causes the fish to jump out of the water.

    Aquarium fish, on the other hand jump for other reasons. The marbled hatchetfish is an accomplished jumper and unless your tank is securely covered, the hatchetfish will jump out of the tank. The marbled hatchetfish (Carnegiella marthae ) feeds on the surface, and in the wild are known to jump out of the water to dislodge any insects that may be crawling on any low hanging leaves or branches. Once the insect hits the water, the hatchetfish has an easy meal. Another popular tropical fish that is known to jump out of the water is the African butterflyfish (Pantodon buchholzi). The African butterflyfish lives near the surface and can jump out of water to capture prey or escape from predators. It also has eyes that enable it to see above and below the water's surface.

    Tropical fish jumping out of water can also be due to bad water quality in the fish tank. Improperly cycling your aquarium can cause fish to jump out as can high concentrations of ammonia or improper pH levels. Fish do breathe oxygen, and when water is dirty, there is less oxygen in the fish tank for the fish to breathe. Lack of decorations or hiding spots can contribute to fish jumping. Other fish that are known to jump out of their tanks include comet goldfish, killifish, (which tend to jump from water puddle to water puddle in the wild), and on the saltwater side, firefish are known jumpers. Koi, the most popular pond fish, have been known to jump out of the water. If you keep fish that jump out of water, such as the hatchetfish or African butterflyfish, try and reduce this capability by adding floating plants and decorations that would inhibit their capability to gather speed to jump out. And keep your aquarium covered with a secure lid.
