Vet Q & APower went out! How to oxygenate my fish tank without electricity?
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:

Most fish will come to the surface for air, but they really do need dissolved oxygen to thrive. Good luck!
