I would recommend using an aquarium thermometer to check the starting temperature and that the heater is working correctly. The heater should have a thermostat which switches on and off to keep the temperature constant. You can leave your fish in the tank during this process if you can monitor with a thermometer.

You can float it in some warm tap water but it will need to come out of the bag before oxygen levels drop and waste levels rise. Hot water bottles or a light over the tank may also keep temps out of dangerous ranges until you replace the heater. Buy two and keep a spare ready just in case.

Thanks for reaching out about you fish. It is believed to be a Comet goldfish. Water quality and nutrition is the key to success. Testing water parameter for pH, ammonia, nitrite and nitrate will give you guidance for a healthy environment. Purchased food should be rotated out every 3 months as vitamin C and other nutrients degrade over time. Trying to maintain water temperature can be challenging with out a heater, but most fresh water fish tolerate some changes. Good luck.

Guppies or Neons are excellent "starter" fish. Care is simple and they are inexpensive. A standard 10 gallon tank is recommended to start. Most people don' t realize the amount of "work" needed to maintain a tank. Filter maintenance, monitoring water chemistry, water changes, monitoring fish health and providing a balanced diet are just a few items that need regular attention to keep a tank thriving. Even though fish aren't as cuddly as cats and dogs, they do have their own personalities and even respond to their owners, especially at feeding time! Studies have shown that simply watching fish in a tank can lead to a reduction in both heart rate and blood pressure. It is quite relaxing.

Thanks for reaching out about your fish. Clove oil (eugenol) is approved in the United States as an anesthetic for fish, no sure about Norway. Overdosing on anesthesia is probably the most humane. Freezing or other methods are not acceptable. Fish veterinarians might have access to tricaine methansulfonate (MS-222) another approved anesthetic for fish. A fish veterinarian might also be able to diagnose and treat a problem. Age is not a disease. Good luck.
