You can, but you should probably make sure you have it at the right temperature for them. I'd say just get it back to the temperature...(Could take a while) them put them in.
Condensation.
it depends on what type of fish.a goldfish has to be in room temperature water.
I don't know if it is normal or not, but my sister had goldfish that would jump out of their tank when she would walk into the room. She would have to scoop them up and put them back in.
It's probably gasy, or flatulent. Try changing to another feed.
Goldfish usually do not eat their own feces; sometimes they confuse it with food, but they will normally spit it right back out. It won't harm them since it's basically the byproduct of the food you feed them, but make sure you are cleaning your tank every week with a water change to remove all the waste.
Goldfish jump out of the water for a variety of different reasons. Some gold fish need more oxygen than what is in their water for example.
Condensing is the process of changing water vapour to liquid water.
If it does that it's dead
The snack that smiles back
Ice melting back into water.
yes, you can bring a goldfish back to life if you rub jelly all over it and then sprinkle some sugar over it. This will then recall its sweet tooth and make it want to eat itself. Congratulations, your goldfish has been brought back to life.
People consider Goldfish as good friends too. But they are fishes and cannot socialize back.
