That depends entirely on the type of fish that are in the tank. If you have tropical fish, temperatures ranging from 75-82 degrees Fahrenheit is about perfect. Freshwater Fish are typically more forgiving of temperature differences than saltwater or oceanic fish tend to be. If you have common gold fish or other non tropical fresh water fish then room temperature or about 64-76 degrees is about perfect.
Between 75 and 80 f
Yes it is important to have a thermometer in your fish tank. The temperature of the water should be between 75-80 degrees.
A heater can raise the temperature of a fish tank if needed
Placing a thermometer in your fish tank is important to monitor the water temperature. It helps ensure that the water is within the optimal range for your fish species, as fluctuations in temperature can stress or even harm the fish. Regularly checking the temperature can also help you detect any issues with your tank's heating or cooling system.
The temperature of the water depends on the type of life/fish you intend to keep in the aquarium.
You should look to getting a heater to properly treat the fish, otherwise it may not get better
Depends on the fish. You need to be more specific.
If you are going from the pet-store's tank to yours you should place the whole bag into your tank for at least 30 minutes then release the fish. If you are going from your tank to another tank you should wait until the tanks are the same temperature then go from one tank to another.
The water temperature varies with the type of fish, but normally it should be about 75 degrees. Most aquarium heaters do a good job of keeping the temperature at this point. If your fish get sick you may want to raise the temperature to about 82 degrees.
The water in the tank that you are transferring the angelfish to should be the same temperature and PH of the old water.If you are adding them to your tank from a fish store, then you should acclimate the fish first by floating the bags in your tank, and every so often add a bit of your tank water to the water in the bag to avoid temperature or PH shock.
To determine if the temperature in your tropical fish tank is too hot, check the ideal temperature range for your specific fish species. If the temperature is consistently above this range, it may be too hot for your fish. Adjust the temperature accordingly to ensure the well-being of your fish.
Betta fish will not be harmed if they are in a filtered tank. If the new tank is about the same size as the old tank you should use the old water or most of it in the new tank. If the new tank is larger so you have to add lots of new water then you should fill the new tank with the new water and let it sit (preferably with the filter running) for two or three days before adding the fish. Also when you move the fish make sure the new tank is at the same temperature as the old tank.
