My fish won't eat after traveling. Is it stress, new food, or water?

Updated On September 23rd, 2025

I brought my two fishes inside a bottle for 2 hours while I travelled back home from hostel. Mistakenly I forgot to take their food along with. I also didn't know what brand I was feeding so I bought Optimum fish food to feed them. But they aren't eating the food. Are they stressed due to the journey or the food isn't correct for them. What should I do please suggest.

They may be stressed from the trip, the water may be too cold (low temps can affect appetite in fish) or the water chemistry may be off. Consider a partial water change. Use only conditioned water that is temperature matched to prevent further stress or shock. The fish food is fine. They will likely eat it once conditions are corrected and they settle down.
