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!

Check water chemistry first. Use a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for an absence ( 0 ppm) of ammonia and nitrites with nitrates at 20 ppm or less. Perform partial water changes, no more than 30% at a time, to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. Check water temp as well. Any of these can drive a fish to the surface. The "flashing" (darting about) can be due to infection (bacterial, fungal or parasites). Consider a broad spectrum antibiotic or an "all in one" product to treat multiple infections. Look in the Aquarium section of the local Petco for options. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.

Begin by submitting a water sample for quality testing. Most pet stores will do this for free or a nominal fee. High ammonia levels, PH imbalances may be responsible for that. Oxygen concentration and quality of the filters should be determined as well. Lack of oxygenation could be the cause of it. If water quality is good and there are no major imbalances, Bubbles should examined to look for any sign of bacterial/fungal infection and eventually water should be treated. Please do not hesitate to contact us again on the forum or by requesting a consultation (where you can post pictures ) if you have any more questions or to discuss it any further.

Pimafix is an acceptable "natural" antifungal treatment. Melafix is for bacterial infections. Kanamycin, erythromycin or metronidazole are good broad spectrum antibiotics. Fungus Cure (by API) is an excellent antifungal. You can find these medications in the aquarium section of most pet stores or even online. Follow label directions carefully and remove the carbon filter insert during treatment if indicated. The cornerstone of any treatment is to first maintain pristine water quality and stable chemistry.

48 hours is not long enough for a tank to properly cycle. Several weeks to a couple months are needed for beneficial bacteria to populate the substrate and filter. These bacteria break down wastes (ammonia, nitrites, nitrates) that are harmful to fish and can promote bacterial blooms resulting in cloudy water. The overfeeding likely contributed to the bacterial bloom. You can cycle with or without fish, however cycling with fish will increase the risk of loss. You'll need to monitor chemistry using a liquid test kit. The kits with strips are not as accurate. Perform partial water changes, no more than 25%, every few days or if ammonia levels begin to affect fish. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Feed them every other day. Normally, you would add one fish at a time but that isn't possible for you now. Monitor chemistry and perform water changes until ammonia and nitrites are 0.25ppm or less and nitrates are 40ppm or less. This
