Q: My fish are jumping out of my water garden. Is there any reason for this? How do I get them to stop? Several Customers
A: Fish will jump out of the water for what seems to be no reason at all, but sometimes that isn t the truth. One reason for this jumping is lethal ammonia levels. As fish excrete waste, ammonia levels begin to rise and if sufficient nitrifying bacteria are not present within your filter to breakdown this ammonia, it can become extremely deadly for fish. Constant high levels of ammonia will cause burns on the fish s gills, thus causing them to want to jump out of the water to escape the pain. If your fish are jumping out of the pond, immediately test for high ammonia levels using an. Doing a 20% to 25% water change as well as adding will help to bring ammonia levels down. Another possible reason, is low oxygen levels. Usually the fish will seem to gasp for air on the water s surface but they have been known to also jump out of the water as well. Use an oxygen test kit to test for proper oxygen levels and make sure during the warmer months of the year you have an running in your water garden. Another cause of low oxygen levels is after using an algaecide to kill off algae.
When algae dies it takes oxygen from the water. If there is an abundance of algae and all of it is killed off in one treatment, there is a possibility for the oxygen levels to get extremely low. Doing a 20% to 25% water change is a quick short-term fix to get fresher, oxygenized water into the water garden. As the above happens, the stress level of the fish can rise, it is always a good idea to add to your water garden. Pond salt will help the fish calm down as well as help to protect them against common fish diseases. Fish are known mostly for swimming in water and not jumping out of the water.

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.
