  • Adding fishes more than fish tank capacity

  • This is the most common mistake that most of us made. Remember, a new fish tank is like a biological slate that you are providing to your fishes. Moreover, there are some microbes in water that filter the water and create a Balance PH of water for fish to survive. So when you add too many fishes to your fish tank, it means there will be a lot of fish waste, and microbes will become unable to filter water properly. As a result PH of water disturbs and there will be a high level of ammonia and nitrate in the fish tank. 

  • No Testing of water:

  • Another thing that you can face is the loss of new fishes. As we mentioned, the ammonia or nitrate level of a fish tank can increase. Apparently, you will not see any sign of water distress. Fishes that are already part of this water may become adopted to this water and not show any sign. But on the addition of new fishes, you can see severe results. Maybe you lost your new fishes as they were not able to adjust to polluted water. So what is the solution to this problem? The most reliable method to avoid such kind of issues, you can do testing of fish tank water.

  • Overfeeding of fish

  • Feeding fishes properly and on time is a caring way, however overfeeding is harmful for fishes.. When you go nearer to them they come on the top and show their anger and hunger. Fishes are always hungry no matter where they are, whatever in the sea, river, pond, or aquarium. They always look hungry so you don't need to worry about it. Uneaten food dissolves in the water and reacts with water and changes its chemistry, it could cause the accumulation of ammonia and nitrites, it can stress fishes and could be toxic form them. Simply, we can say that overfeeding may cause fish to lose.

  • Buying a filter that is too small

  • You can say filters are necessary for fish tanks. The main purpose of fish tank filters is to clean and make more hygienic water for better fish life. They are rated as the size and kind of fishes in the fish tank. It cleans the water and filters water from ammonia and nitrites and aerates the water so your fish can breathe and live healthily. So for healthy environments for your fishes always buy a filter, a little larger in dimensions. A larger filter will do the filtration process efficiently.

  • Lightening of fish tank all-day

  • This is another common mistake that many fish tank owners make. Like humans fishes also need some resting period, so always light on the fish tank is not appropriate. All-time lightening of fish tanks will emphasize the growth of algae and your fishes can also stress out. For this reason, it is necessary to provide a consistent light cycle to your fish tank. For instance, you can put your fish tank light to a timer for a proper cycle of light for your fish tank.

  • Not changing water properly:

  • I saw many people using the method of topping off instead of changing the water of the fish tank. Topping off is the evaporation of all the water from the fish tank.  If you will not properly change the water of your fish tank then the PH level of water will disturb. There will be more nitrates and phosphate pollutants in water, which can cause disease in your fishes. There is a need to change about 10% water in your fish tank every week.

  • Overcleaning of Fishtank

  • Overcleaning of your fish tank can kill beneficial bacteria of your fish tank. Avoid using too many chemical cleaners and over scrubbing of your fish tank oftenly. If you feel your fish tank needs cleaning after every 1 or 2 weeks then there is a need for change of filter. This usually happens, when you use a small filter for your fish tank.

  • Introducing fishes to a new fish tank

  • A new fish tank, usually not a perfect biological environment for fishes. After 3 to 4 days there is proper creation of a biological clean slate. So never buy a fish tank and fishes on the same day. Firstly buy a quality fish tank, and after 3 to 4 days introduce fishes to your tank.

  • Fish types

  • Not all fishes are compatible with all types of water. Like there are some fishes, which require lower PH than tap water. Moreover, the same thing with feeding also. Some fishes need proper food than other types of fishes. So it is important to compare all the fish tank factors and fish types.

  • Low-quality fish tank

  • You get what you pay for, this saying works for the fish tank industry. A low-quality fish tank compromises the quality of life of your fishes. For this reason, we will never recommend you compromise on the quality of the fish tank. For a fish tank, you should spend some good amount of money as we can't compromise the well-being of our fishes.


    Having a fish tank is a great idea and a fun activity. But, it is also necessary to avoid common fish tank problems and mistakes that you can make. I Hope, our article helps you to understand the problems and solutions clearly.
