Before you buy any fish, you will need to set up the tank. A basic set up includes: a tank, filter, hood/light, heater, gravel and some decor. The tank should run without fish for at least 4 to 6 weeks. This gives it time to cycle. The Nitrogen Cycle is critical to the health of the tank and any fish you will be keeping. During this time, beneficial bacterial will populate the filter and substrate (gravel). These bacteria will be responsible for breaking down fish wastes and other wastes (uneaten food, dead plants, etc.). You will need a home test kit to monitor water chemistry (ammonia, nitrites, nitrates, pH) or you will have to submit water samples for testing. Most pet stores will do this for free or for a small fee. At first, you will see high levels of ammonia and nitrites. Over time, as bacteria grow, these levels will drop. When ammonia and nitrites are at 0 ppm and nitrates are below 20 ppm, you can consider adding fish. Regular (every 1 or 2 weeks) partial water changes as we

Check the water chemistry and quality first. Poor quality can predispose him to infection. Use a home test kit or submit a water sample for testing. Your local Petco may do this for free or for a small fee. If ammonia and/or nitrite levels are elevated, perform partial water changes until both read 0 ppm and nitrates are 20 ppm or less. Use only conditioned water that is temperature matched to prevent further stress or shock. Providing pristine water quality is the foundation for treatment and healing. Check the water temperature since low temps can affect appetite and activity in fish. If the water is too warm, it can also affect activity since warm water does not hold as much oxygen as cooler waters. Fast the fish for 2-3 days then feed tiny bits of cooked and shelled green peas. This will aid in defecation if there is constipation. Plain aquarium salt (not table salt or Epsom salt) can be used for most fish as a general tonic to reduce stress, improve gill function, treat minor in

Hi there! The fish will probably be ok for a day, but if the power doesn't come back on, you should consider purchasing a battery-operated aerator. I highly recommend that all fish owners keep one of these on-hand for situations like this. I don't know if this person ships to Turkey, but a similar product would be fine, too: https://www.ebay.com/p/Rapala-Battery-Powered-Aerator-Model-Raertr-c/1000293148?iid=371986500727 Most fish will come to the surface for air, but they really do need dissolved oxygen to thrive. Good luck!

You should have Diphenhydramine, that is the same as Benadryl, just not the brand name. That is the active ingredient in Benadryl. You should have an equivalent to this where you are. Check drug stores and ask someone and I am sure you will be able to find an alternative. As for the fish oils, you should be able to perform a simple online search for canine fish oils or visit any local pet store near you that offers pet supplements.

Water conditioning can be complicated and I recommend to stop by your local aquarium store. They are most often familiar with the local water quality and can give recommendations specific to your location. Some areas need buffering solutions to help control things like the water pH. Here are a few links which may help answer some of your questions about water condition: https://www.aqueon.com/articles/freshwater-aquarium-water-quality https://www.petcoach.co/article/aquarium-water-management-alkalinity-vs-water-hardness/ Before moving your goldfish, make sure all the conditions are appropriate for goldfish: https://www.aqueon.com/information/care-sheets/goldfish https://www.petcoach.co/article/how-to-help-your-new-goldfish-thrive/ I hope this helps and please feel free to post any additional questions.
