Goldfish are generally easy to take care of, but when problems arise, finding a solution can be difficult. One thing that causes great concern is when you find your goldfish laying on bottom of the tank.
It is important to understand there is no one quick answer to why this is occurring.
Treating the goldfish with all kinds of different medications before knowing the actual cause of the problem is definitely not the answer.
It’s best to rule out some possible (easily treatable) causes first.
Reasons why goldfish lay on the bottom of the tank
- Swim Bladder Problem
- Overcrowding in the tank
- Aggressive fish behavior in the tank
- One of the reasons why you might find a goldfish laying on bottom of the tank is because of a swim bladder problem. In healthy fish the swim bladder fills with blood gasses to allow the fish to swim to the top of the water. Problems with the swim bladder may keep the blood gasses from filling leaving the goldfish stuck at the bottom of the tank.

- This could also be causing the goldfish to gravitate to the bottom of the tank.
In both of the above cases feeding the goldfish peas could help remedy the problem. Peas have been known to help improve both constipation and swim bladder problems.
- Overcrowding in the tank is another reason a goldfish lays on the bottom of the tank. Keeping too many goldfish in a small tank causes the fish to become stressed. Also, the more fish in a tank the higher the chances are of ammonia or toxins infecting the water.
- Tanks with high nitrate or ammonia levels can be deadly to goldfish.
It is best to keep only 2-3 goldfish in a 10-gallon tank. This will minimize the chance of overcrowding and risk of disease. It’s essential to regularly check ammonia and nitrate levels and keep clean water in the tank.
- Watching the behavior of the goldfish could provide the answers the owner is looking for. If there are other fish in the tank that are aggressive, a goldfish may go to the bottom of the tank to hide. There’s nothing physically wrong with the goldfish.
Removing the aggressive fish or placing the timid fish in a floating basket, may solve the problem.
Overall, there are many reasons why you might find goldfish laying on bottom of the tank. It is not necessarily a sure sign of dying.
Some problems may require medication, and others may just need an adjustment to the environment.
It’s important to try to figure out the exact problem before starting a treatment that may not be necessary.
