Water Tests are perfect but my Fish Keep Dying

If water tests are perfect, that does not mean that your fish is healthy. There might be many other reasons that make your fish keep dying in the aquarium. Some of the biggest reasons for fish death are stress and dirty water, while some healthy fish can fight off the infection and get healthy and many other weak fish die within a week. Therefore, it is important for us to watch for the signs of stress in our fish.

Treat sickness before it starts

To prevent fish from getting sick in the first place, you should be taking your water tests regularly and treating any issues that come up before they become an epidemic.

Stress on fish eventually results in their death. It's Just a matter of time. It may take a few days or weeks, but one thing is certain, stress is not an instant killer.

Your tank should be set up to suit the fish that you keep. A freshwater fish will die in a saltwater aquarium. Similarly, a fish that prefers warm water will likely die in cold water.

Ich- It is a parasitic infection that passes in one fish from another fish, a common parasite that causes saltwater ich, also known as white spot disease. Saltwater is easy to identify by the characteristics of white spots, around 0.5 to 1.0 millimeters in size, that typically appear on a fish's fins and skin, that typically appear on a fish's fins and skin.

Fin rot- It may occur due to some injury that happened while fighting off with aggressive fish or due to unclean and inappropriate water quality.

This means an appropriate environment, with good water quality, and a healthy diet. Your fish's fin will start to regrow, you may see clear or white tissue around the tail. This is new skin growth and completely normal. Whereas if you see red tissue it is a sign of continued infection.

Check pH levels regularly 

pH levels must be balanced for healthy fish. If you notice your fish start to die in large numbers. It could be a sign that your water's pH levels are too high or low. Saltwater fish require a pH level between 8.0 and 8.4 for optimum health.
